Thermosetting compositions based on polymers containing acid anhydride groups

摘要

A thermosetting composition consists essentially of a mixture of (A) a polymer containing acid anhydride groups, (B) a molecular sieve being partially loaded with at least one amine, and (C) a filler capable of releasing water upon heating at a temperature above the processing temperature of the mixture of (A), (B) and (C). The processing temperature is chosen so as to be below the desorption temperature of the amine from the molecular sieve. The composition is particularly useful in making hot melt adhesives and sheetings of electric cables.
