Novel Poly(imide—siloxane) Polymers and Copolymers

Open publisher page 4 citations

Abstract

The synthesis and properties of poly(imide—siloxane) polymers and copolymers based on 5,5′-bis(1,1,3,3-tetramethyl-1,3-disiloxanediyl) norbornane dicarboxylic anhydride are described. High-molecular-weight thermoplastics and elastoplastics were prepared readily in solution from aromatic diamines, organic dianhydrides, and this unique anhydride-terminated siloxane. The thermal and mechanical properties of a variety of copolymer compositions are described. Average siloxane block length and overall siloxane content had the greatest effect on these properties.
