AMELIORATIONS AUX COMPOSITIONS ADHESIVES RESINEUSES THERMODURCISSABLES,OU SE RAPPORTANT A CES COMPOSITIONS

摘要

A thermosetting adhesive is made from a saturated highly aromatic polyester resin derived from a low molecular weight dihydric or trihydric polyol, a difuntional aliphatic acid or its corresponding halide or anhydride and a polyfunctional aromatic acid, or its corresponding halide or anhydride, in specified proportions. The adhesive can be applied to fibrous backing to provide a pressure sensitive tape that can be cured to a rigid thermoset state with excellent physical strength and high temperature electrical insulating properties.
