Physical Chemistry of High Polymers - Surface Properties of Interpenetrating Polymer Networks

摘要

We have investigated the surface chemistry of interpenetrating polymer networks (IPN) as they relate to the development of a new class of improved, thermally stable adhesives with unusual surface and adhesive properties. We have carried out mechanical, thermal, wetting, permeability and electron microscopic investigations of polyurethane epoxy and polyacrylate IPN's. We have studied the minimum critical surface tension as a function of network composition, as observed in polyurethane-epoxy IPN's and transport properties in such homogeneous and partially inhomogeneous polymers.(Author)
