Application of Novel Polyvinyl Chloride Molecular Weight Regulator
WANG Guo-wen.(Zhuzhou Chemical Group Lt.d; Zhuzhou 412004; China)
Abstract:Through analysis on mechanism of mercaptoacetate 2 ethyl hexyl resina telomerization and on the effect of telomeric experiment with conclution.It was found that the effect of novel polyvinyl chloride molecular weight regular to 2 eythl hexyl mercaptoacetate resina is obvious in keeping back ploymerie.The flow process adding is only suitable to producie low plomerize degree resina.
Key words:chain transfer reaction; ploymeric degree; telomerization; heat stability
