Thermal stimulated current study of core‐shell impact modifier/PVC blends

Abstract

This study examines the efficacy of core-shell structure impact modifiers, having different particle sizes and core/shell compositions, for modifying PVC's impact strength. The core and the shell's main compositions are polybutyl acrylate and polymethyl methacrylate, respectively. Also, the TSC is used to obtain the fundamental states of the blended impact modifier/PVC systems, thereby allowing them to be correlated to the above observed efficacy. Results of this study can provide valuable information toward exploring the feasibility of using the TSC data as a product development guide for designing PVC impact modifiers.
