STYRENE - ACRYLONITRILE RESIN WITH ENHANCED TRANSPARENCY PROPERTIES AND MANUFACTURING METHOD THEREFOR

摘要

A process for producing a styrene acrylonitrile (SAN) resin having enhanced transparency or reduced haze includes exposing styrene monomers and acrylonitrile monomers to l,l-Di(tert-butylperoxy)cyclohexane, the l,l-Di(tert-butylperoxy)cyclohexane having a concentration between approximately 5 - 500 parts per million (ppm) relative to a total weight of the styrene monomers and acrylonitrile monomers; initiating polymerization reactions involving the styrene monomers and the acrylonitrile monomers exposed to the the l,l-Di(tert-butylperoxy)cyclohexane; continuing the polymerization reactions for a polymerization time period; stopping the polymerization reactions; and obtaining a SAN resin having a haze value significantly less than approximately 0.50 (e.g., less than or equal to approximately 0.45, 0.40, 0.35, 0.30, 0.25, 0.20, 0.15, or 0.10).
