交联产率的剂量依赖性测定的聚(氯乙烯)和聚乙烯与烯丙基多官能单体(PFM)的辐照组合物。因此,使用了差示交联产率G* c的概念。的剂量依赖性的G* c有一个最大的调查系统。测定了烯丙基和PFM分子的电流消耗。在所研究的系统中,网络形成的过程中进行通过链交联的接枝链的聚-PFM。
The dose dependence of crosslinking yields was determined for irradiated compositions of poly(vinyl chloride) and polyethylene with an allylic polyfunctional monomer (PFM). Therewith, the notion of the differential crosslinking yield G* c was used. The dose dependence of G* c has a maximum for the investigated systems. The current consumption of allylic groups and PFM molecules was determined. In the investigated systems, the process of network formation proceeds through chain crosslinking of graft chains of poly-PFM.
