Microscopic Studies on Degradation of the Cross-linked Polymers. (II)

Experimental Results for EPM

Abstract

The theoretical equation derived in the paper (I) was compared with the experimental results of EPM (ethylene-propylene co-polymer) as model polymer. As the results, it was found that the both scissions have expectedly occurred for this sample in air at high temperature and k=1 or the probability of both scissions is equal.
These results were infered from the fact that in the chemical structure of EPM cured with the peroxide curing agents, the both chemical bonds of main chain and cross-linking site are the same as C-C bond.
