- 英文摘要:
The graft copolymerization of styrene and acrylonitrile onto chlorinated
polyethylenes were carried out by method of suspension polymerization. The
separation of grafted polymer species together with poly(styrene-co-acrylonitrile)
from ungrafted chlorinated polyethylene was effected in N, N-dimethylformamide.
From the chlorine contents and number average molecular weights (Mn) of various
fractions, the degree of grafting and grafting efficiency were estimated. The
results showed that both can be improved considerably in the presence of a chain
transfer agent. - 中文關鍵字: --
