PRESSURE-SENSITIVE ADHESIVE (VERSIONS) AND FOAM MATERIAL Russian patent published in 2013 - IPC C09J133/00 C09J133/04 C09J4/06 

FIELD: chemistry.

SUBSTANCE: described is a pressure-sensitive adhesive (versions) based on a mixture which contains an acrylate polymer which contains at least one cross-linkable functional group selected from a group comprising silyl, hydroxyl, carboxyl, isocyanate, vinyl, methacrylate, epoxyl, amino group, merapto group and acetoacetyl, and having glass transition temperature below 20°C, and molecular weight of 20000-500000, an oligomer which is liquid at room temperature, having glass transition temperature below 25°C and containing at least one cross-linkable functional group selected from a group comprising silyl, hydroxyl, isocyanate, vinyl, methacrylate, epoxyl, amino group, mercapto group and acetoacetyl, and at least one cross-linking agent, wherein at least one acrylate polymer and the oligomer are cross-linked in the presence of each other. Also described is foam material based on a mixture which contains said pressure-sensitive adhesive and foamed microspheres or a foaming agent.

EFFECT: obtaining a pressure-sensitive adhesive which is characterised by high adhesion in a wide temperature range.
