Title:
VINYL CHLORIDE-BASED POLYMER AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2016/047953
Kind Code:
A1
Abstract:
The present invention relates to a vinyl chloride-based polymer having superb thermal stability due to suppression of heat- or ultraviolet light-induced hydrochlorination, and a method for producing the polymer. The vinyl chloride-based polymer according to the present invention can markedly suppress the heat- or ultraviolet light-induced occurrence, thus improving thermal stability to prevent discoloration or change in physical properties. Moreover, the production method according the present invention adds a modifier to the polymer at the final stage of polymerization, thereby imparting high thermal stability to the vinyl chloride-based polymer without causing deformation.
