早在1956年Oster就发现聚乙烯在某些光敏剂的存在下能够被紫外光所交联,但由于紫外线的穿透深度等方面的限制,光交联的方法一直未能得到实际应用.近年来R(?)nby等人对此进行了一些重要的改进,使之可以与现行的高能辐照法和热化学法相媲美,因而工业前景十分乐观.本文简要地介绍了对这一方法的实用性所进行的多方面的实验结果。 As early as 1956, Oster found that polyethylene can be crosslinked by ultraviolet light in the presence of some photosensitizers, but the method of photocrosslinking has not been practically applied due to the limitation of UV penetration depth, etc. In recent years, R (?) Nby, who made some important improvements to this, so that it can be comparable with the current high-energy irradiation and thermochemical methods, so the industrial prospects are very optimistic.This article briefly introduced the practicality of this method Many aspects of the experimental results.
