PROCESS FOR PREPARING EXPANDED COPOLYMERS BASED ON POLY(METH)ACRYLIMIDE COMPRISING AN ADHESION PROMOTER

摘要

The invention describes a method for producing a foam moulding from poly(meth)acrylimide, an adhesion promoter or an adhesion promoter mixture and optional auxiliaries, comprising the following steps:
grinding a polymeric moulding made of poly(meth)acrylamide,coating the grindings obtained in the preceding step with an adhesion promoter,introducing the coated grindings into a mould,optionally adding the auxiliaries,heating the mould,cooling the mould below the foaming temperature, anddemoulding the foam moulding.;The resulting foam moulding has outstanding mechanical properties and is suitable for applications including as a component in the production of space, air, water and land vehicles.
