NOVEL POLYMERISATION AND/OR CROSS-LINKING INITIATOR SYSTEMS COMPRISING AN ONIUM BORATE AND A BENZOPHENONE

摘要

The invention concerns the field of polymerization and/or cross-linking reaction catalysis by cationic process of monomers, oligomers and/or polymers. In particular, novel polymerization and/or cross-linking initiator systems comprising at least one onium borate and at least one benzophenone are described to satisfy the ever greater exigencies of productivity and manufacture. The initiators are used in particular for preparing resins and/or composite materials based on an organic and/or silicon matrix or optionally a matrix of acrylic monomers, oligomers, or polymers.
