摘　　要：在没有溶剂介质参与的高分子聚合反应中,高分子凝聚态的变化与化学反应之间的作用关系变得更加直接。以熔融聚合、反应挤出、固相聚合为代表的高分子树脂无溶剂生产技术是集高分子树脂合成、材料加工制备及工程一体化的新兴科学与技术,是当代材料科学领域发展的前沿领域,代表着高分子树脂生产技术发展的必然趋势。本文将上述这三种典型的树脂工业合成技术及相应机理进行了简要的介绍,并分别以聚对苯二甲酸乙二醇酯(PET)和聚乳酸(PLA)的实际生产研究情况为例,展示三种生产技术之间的相互联系,揭示这三种无溶剂型高分子制备技术过程中出现的高分子凝聚态变化与化学反应之间的基本问题,为广大科研工作提供一些有价值的参考。The interaction between the changes of polymer condensed states and chemical reactions becomes more directly in the solvent-free polymer polymerizations.Melt polymerization(MP),reactive extrusion(REX)and solid phase polymerization(SPP)are classical solvent-free polymerization production technologies.The solvent-free polymerization production technology is a new science and technologies integrating polymer resin synthesis,material processing and preparation and engineering.It is the frontier field of contemporary material science,and represents the inevitable trend of the development of the resin production technology.In this paper,the three typical resin industrial synthesis technologies and their corresponding mechanisms are briefly introduced,and the actual productions of polyethylene terephthalate(PET)and polylactic acid(PLA)were shown,and the relationship between the three production technologies were also exhibited.In here,the basic problems of polymer condensed state changes and related chemical reactions were revealed by these three solvent-free polymerization technologies,and some valuable references for scientific researcher were provided.
