Process for improving biodegradability of PVC.

摘要

The present invention relates to a process for dehydrochlorinating polyvinylchloride by heating the starting materials PVC and neutral liquid water at temperatures from about 200 DEG C up to the critical temperature of water at autogenous pressure. The process has utility in recycling by enabling PVC to be dechlorinated specifically by a means that does not release chlorine gas.
