摘要：
The gel formation of PVC and post-chlorinated PVC samples in DOP (di-(2-ethylhexyl)phthalate) was studied by measuring the storage modules as a function of time/frequency. Random chlorination of PVC in solution completely suppressed gelation when more than 13 mole % additional chlorine was introduced: Chlorination of PVC aids in understanding the mechanism of gel formation and reaffirms the relation between gel formation and crystallizability, but no firm conclusion can be drawn with respect to the origin of crystallinity in commercial PVC samples.
