The purpose of the designed experiment is to stimulate students' initiative and innovative consciousness, and cultivate students' ability to think independently, comprehensively apply knowledge, ask questions and solve complex problems. The basic requirement of this course is 1. Before the experiment, students should carefully read the contents of the experiment, understand the purpose and requirements of the experiment, and write a preview report, which includes the principle and technology of the experiment, the order and matters needing attention of the experimental operation, the format of data recording, and the difficult problems in the preview. Teachers should check students' preview reports, ask necessary questions and answer difficult questions. Students can only do experiments if they meet the preview requirements. 2. After the experiment, students should check whether the measuring instruments and reagents meet the experimental requirements, make all kinds of preparations for the experiment, and record the experimental conditions at that time. During the experiment, students are required to observe the experimental phenomena carefully, record the original data in detail and strictly control the experimental conditions. Throughout the experiment, we maintained a rigorous and realistic scientific attitude, a cooperative spirit of solidarity and mutual assistance, and actively explored scientific laws. 3. After the experiment, students must submit the original records to the teacher for signature, then correctly process the data and write the experiment report. The experimental report should include: experimental purpose and requirements, concise principles, experimental instruments and conditions, specific operation methods, data processing, results discussion and reference materials. Experimental discussion is an important part of experimental report. Teachers should guide students to reflect on the experience gained through experiments, analyze, summarize and explain the experimental results and phenomena, and encourage students to further carry out experiments. 4. Comprehensive and designed experiment requirements: The designed experiment is not the repetition of the basic experiment, but the perfection and deepening of the basic experiment. Under the guidance of teachers, students choose experimental topics, apply the principles, methods and techniques of physical chemistry experiments they have learned, consult the literature, independently design experimental schemes, choose reasonable instruments and equipment, assemble experimental devices, conduct experimental operations independently, and write experimental reports in the form of scientific papers. Three. Experimental methods and requirements The experiment is divided into two parts. 1. Five confirmatory polymer chemistry experiments (20 class hours), five confirmatory polymer physics experiments (20 class hours), 1 comprehensive experiment (16 class hours), 1 design experiment (16 class hours). The program topic of the design experiment is to choose the topic you are interested in from the design experiment topics provided by the teacher, or to determine the experimental topic yourself. Consult literature, including experimental principles, experimental methods, instruments and equipment, and compare, synthesize and summarize different methods. Design scheme The design scheme should include the schematic diagram of the experimental device, detailed experimental steps, required instruments, drug list, etc. Feasibility demonstration A week before the start of the experiment, teachers and students are invited to put forward the existing problems and optimize the experimental scheme. Experimental preparation: Make preparations for experimental instruments and drugs. A week in advance in the lab. During the implementation of the experiment, we should pay attention to observing the experimental phenomena and investigating the influencing factors at any time, and repeat the experiment until it is successful. Data processing comprehensively processes the experimental data, makes error analysis, writes an experimental report with certain opinions according to the format of the paper, and makes an exchange defense. The requirement for designing the experiment is 1. The investigated documents include at least one foreign language document. 2. Students must design experiments by themselves, combine instruments and complete experiments, so as to cultivate the ability to solve practical problems by comprehensively applying the chemical experimental skills and basic knowledge they have learned. Four. Polymer chemistry experiment is an independent course, involving a wide range of contents, so it is necessary to carry out examination. The test is mainly based on the usual experiments, and the experimental operation test is conducted at the end of the period, totaling 1 class hour, with a score of 50%; Usually, the score of 50% includes preview report, experimental attitude, operational skills and experimental report.

Introduction of comprehensive and designed experimental project 1: synthesis and performance analysis of silicone modified styrene-acrylic emulsion (design) (teacher Song Jianhua) 1. Guiding ideology It is the development trend of the world coating industry that water-based coatings gradually replace oily coatings, which is due to the limitation of organic volatile matter (VOC) emission. The advantage of waterborne coatings is that water is used as solvent, which can avoid all kinds of unfavorable factors such as flammability, toxicity, high cost and construction conditions caused by using organic solvents. In addition, water-based coatings have excellent anti-rust performance, can be used on metal surfaces, and their luster is close to that of general solvent-based coatings, and their stability is also good. Vinyltriethoxysilane-styrene-butyl acrylate-methacrylic acid (A-15/-st-ba-MAA/SDS-DNS86/H2O) was prepared by step-by-step radical polymerization with water as solvent and sodium dodecyl sulfate-alkyl vinyl sulfonate (SDS as emulsifier and potassium persulfate as initiator). 2. Experimental purpose and requirements Experimental purpose: Firstly, the effects of temperature, different proportions and emulsifier content on emulsion properties were investigated, and the emulsifier dosage-viscosity curve, emulsifier dosage-particle size distribution curve, solid content-particle size distribution curve, solid content-viscosity curve and solid content-water absorption curve were obtained. Secondly, the improvement of solid content of emulsion was studied, and the highest solid content could reach about 60%. Finally, the structures of various latex films were characterized by infrared spectroscopy, the thermal properties of various latex films were analyzed by thermogravimetry, and the glass transition temperatures of various latex films were determined by DSC. Experimental requirements: at least 10 documents were searched, including 1 foreign documents; Students must design their own experiments, combine instruments and complete the experiments. 3.
