CONJUGATED DIENE/MONOVINYLARENE BLOCK COPOLYMERS, METHODS FOR PREPARING SAME, AND POLYMER BLENDS

摘要

A block copolymer comprising at least three consecutive conjugated diene/monovinylarene tapered blocks is provided. Other aspects of this invention include a polymerization process for preparing the block copolymer and polymer blends comprising the block copolymer. The block copolymer and polymer blends exhibit excellent optical and mechanical properties.
