摘　　要：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 (PTFE) has always been regarded as a typical kind of radiation degradation polymer. But, in fact, PTFE can be induced crosslinking by γ-ray or electron beam at some special conditions (free oxygen and a narrow temperature region at 335±5℃).Compared with radiation degradation PTFE, cosslinking PTFE owns a lot of new properties. Some articles concerning with these have been published, which will be systematically reviewed in this.
