[题名] 可熔融加工聚四氟乙烯

[摘要] 本文研究了一种新的可熔融加工的四氟乙烯基聚合物的表征和加工过程。研究了一系列20个实验聚（四氟乙烯）（PTFE）等级，具有相对狭窄的单模摩尔质量分布，包括少量的全氟（丙基乙烯醚）（PPVE；0.034 - 0.752 mol%)。选择这个共聚物的含量范围是为了弥补严格线性的聚四氟乙烯均聚物和商用的、可熔体处理的全氟烷氧基共聚物（PFA）之间的差距，该共聚物通常含有1.5 - 2 mol%的PPVE。

[Title] Melt-Processable Poly(tetrafluoroethylene)s

[Abstract] The present thesis is concerned with the characterization and processing of a new family of meltprocessable tetrafluoroethylene-based polymers. A series of 20 experimental poly(tetrafluoroethylene) (PTFE) grades with relatively narrow monomodal molar mass distributions comprising minor amounts of perfluoro(propylvinylether) (PPVE; 0.034 - 0.752 mol%) was studied. This comonomer content range was chosen to bridge the gap between strictly linear PTFE homopolymers and commercial, melt-processable perfluoroalkoxy copolymers (PFA), which contain typically 1.5 - 2 mol% of PPVE.
