Polyimide of Modified Melt Flow and Toughness
Abstract
Linear aromatic polyphenylene ether sulfideimide (BDSDA/APB) polymer molded, used as resin, and cast into thin films. In effort to improve further both use properties and amenability to process BDSDA/APB, molecular weight of polymer varied by variations in percentage of end capping. Effect of end capping BDSDA/APB determined by measurement of polymer melt viscosity and fracture-energy values for different number average synthesized molecular weights.
