聚四氟乙烯（以下简称为F4）一直被认为是典型的辐射降解型高聚物，但事实上F4在特定条件（无氧及一个很窄的温度区间（335±5℃））下是可以实现辐射交联的。辐射交联F4与辐射裂解F4相比，其性质（如结晶度等）发生了很大的变化，与之相关的文献近几年已陆续发表，对此本文将给予扼要的回顾及总结。
Polytetrafluoroethylene (hereinafter abbreviated as F4) has long been considered as a typical radiation-degradable polymer, but in fact F4 is acceptable under specific conditions (oxygen-free and in a very narrow temperature range (335 ± 5 ° C)) To achieve radiation cross-linked. Radiation cross-linking F4 compared with radiation pyrolysis F4, its properties (such as crystallinity, etc.) have undergone great changes, and the related literature has been published in recent years, this article will give a brief review and summary.
