摘要

改革开放40年来

我国的高等教育得到了巨大发展

高校实验仪器设备变得越来越先进而且越来越齐全

但高校实验内容仍停留在上世纪八、九十年代的编写水准

与目前的科学技术和实验技术发展相比有些滞后

更令人费解的是

某些工科院校的研究生还仍未开设高等实验课

因此

怎样使我国的高校由大变强

从而全面提高研究生的综合实验能力和科研能力

成为制约我国高等教育发展的一个最大瓶颈。本文通过对高分子合成化学自由基连锁聚合反应和逐步聚合反应两个经典合成实验进行深入剖析

阐述了高分子化学实验和高分子物理实验内容的融合贯穿对提高大学生尤其是研究生综合实验动手能力和科研能力的重要性

使同学们牢牢把握高分子材料实验合成、分子量测定、化学结构表征、性能测试等这条主线

即通过一个合成实验

尽可能多些使学生掌握如黏度法或凝胶渗透色谱法(GPC)分子量测试、马尔文激光粒度仪使用方法及粒度分布测试、红外光谱仪及扫描电子显微镜测试等结构表征以及热性能、电性能、力学性能等测试方法

使学生们窥一斑而知全豹

为全面提高研究生的综合实验能力和科研创新能力提供借鉴和推动作用。

Abstract

In the past 40 years

China's higher education has been greatly developed because of the reform and opening up. And the experimental instruments and equipment in colleges and universities have become more and more advanced and complete. However

the experimental content in colleges and universities still stays at the level of compilation in the 1980s and 1990s. Compared with the current development of science and technology as well as the experimental technology

our experimental content lags behind. Even more puzzling was the fact that some graduate students in engineering colleges have not yet set up higher experimental courses. Therefore

how to make the universities in our country from big to strong and so as to completely improve the comprehensive experimental ability and scientific research ability of graduate students has become the biggest bottleneck restricting the development of higher education in our country. In this paper

two classical synthesis experiments of polymer chemistry

free radical chain polymerization and step polymerization

are analyzed in detail. The integration of polymer chemistry experiment and polymer physics experiment is very important to improve the comprehensive experimental ability and research ability of college students

especially for the graduate students. So the students can firmly grasp the main line including experimental synthesis of polymer materials

molecular weight determination

chemical structure characterization and properties testing

et al. It is to make students master as many as possible knowledge such as viscosity method or gel permeation chromatography (GPC) method for molecular weight test

Malvin Laser instrument for particle size analyzer and particle size distribution test

infrared spectrometer and scanning electron microscope test methods

and the analysis methods of thermal properties

electrical properties and mechanics performance et al.

so that the students can know the whole leopard over seeing a spot. At last

this paper could provide reference and promotion for comprehensively improving the experimental ability and scientific innovation ability of graduate students.
