Polymer compositions for multi-stage curing or two-step

摘要

The present invention provides a polymer composition for use at least in surface coating applications and in fabrication of rigid foams with load bearing capacity comprising a base molecule, a linker molecule and at least one initiator compound, said base molecule having at least two differing functionalities, and said linker molecule having a functionality reactive with at least one functionality of said base molecule, the first of said at least two functionalities of said base molecule enabling a first curing stage of said polymer composition by reaction with said linker molecule, and the second and any further functionality of said base molecule enabling second and further curing stages of said polymer composition, said first, second and any further curing stages being capable of activation simultaneously or independently of each other as required. A further provides uses of the polymer compositions of the invention in surface coating and adhesives applications and in the preparation of rigid foams with load bearing capacity.
