Zur kinetik der copolymerisation von methacrylaten mit entkoppelter seitengruppe

Abstract

The copolymerization behaviour of methacrylate monomers with several decoupled side groups was studied depending on the structure of the linked mesogen. Some units (-N=N--, -CO-NH-)in the rnesogen influence the copolymerization reaction in spite of the strong decoupling by a C6-spacer group and lead to retarding effects and to the preferred insertion of monomers with weaker mesogenic interactions. The liquid-crystalline behaviour of the copolymers was not affected due to the relatively small differences in the copolymerization parameters.
