摘要
介绍了高相对分子质量聚四氟乙烯的性能和应用,从不使成长的自由基失活而降低聚合速度及不使链转移发生而降低相对分子质量的观点出发,就影响高相对分子质量聚四氟乙烯制备的原材料等因素作了详细的介绍。建议国内加快研发,开发多种牌号,摆脱依赖进口。
The properties and applications of polytetrafluoroethylene(PTFE) with high molecular weight were introduced.The factors that may influence the preparation of PTFE with high molecular weight such as the raw materials were introduced,based on the points of view including avoiding the slow down of polymerization speeds by avoiding the deactivation of growing free radicals and avoiding the reduction of relative molecular weight by avoiding the transfer of chains.It was suggested that the domestic research speed should be accelerated,multi-brand should be developed and the rely on importation should be got rid off.
