【摘要】：高分子化学是一门实验性很强的学科,是高分子材料合成、加工和应用的基础,也是高分子专业研究生入学考试必考的科目之一,但如何提高学生们的实验观察能力和动手操作能力成为近些年来各高校培养学生的重点课题。而在高分子化学实验合成方法中,悬浮聚合方法由于反应温度低、操作方便、反应过程容易散热、聚合物粒度容易控制、水为分散介质廉价等优点,在橡胶、塑料等高分子材料合成工艺中被广泛应用。本文以高分子化学悬浮聚合实验为例,从"看"、"听"、"摸"、"嗅"多个角度向学生们展示了高分子化学反应在不同反应条件下及不同反应阶段所表现出的实验现象及反应结果,旨在提高学生们的综合实验能力,使之早日踏上科研探索之路。
[Abstract]:Polymer chemistry is a strong experimental subject, which is the basis for the synthesis, processing and application of polymer materials. It is also one of the subjects that must be taken into account in the entrance examination for graduate students majoring in polymer. However, how to improve the students' ability of experimental observation and hands-on operation has become a key issue in the cultivation of students in colleges and universities in recent years. In the experimental synthesis method of macromolecule chemistry, the suspension polymerization method is easy to operate because of its low reaction temperature. The reaction process is easy to dissipate heat, the polymer particle size is easy to control, the water is the dispersing medium cheap and so on the advantage, in the rubber, the plastic and so on high molecular material synthesis craft is widely used. This article takes the polymer chemical suspension polymerization experiment as the example, From the perspectives of "see", "hear", "touch" and "smell", the students were shown the experimental phenomena and results of polymer chemical reaction under different reaction conditions and different reaction stages, in order to improve the students' comprehensive experimental ability. To set foot on the road of scientific research and exploration at an early date.
