Multicomponent interpolymers having alternating sequential structure
Abstract
Abstract A CONJUGATED VINYL COMPOUND HAVING A NITRILE OR CARBONYL GROUP IN THE CONJUGATED POSITION ((b) GROUP MONOMER) FORMS A COMPLEX WITH AT LEAST ONE ORGANOALUMINUM HALIDE OR AT LEAST ONE ORGANOBORON HALIDE, AND THIS COMPLEX REACTS WITH AN OLEFINIC MONOMER ((A) GROUP MONOMETR) TO PRODUCE AN ALTERNATING COPOLYMER. THE PRESENT INVENTION IS BASED ON THE DISCOVERY THAT WHEN THERE ARE A PLURALITY OF THE (A) GROUP MONOMERS AND/OR A PLURALITY OF THE (B) GROUP MONOMERS IN SAID ALTERNATING COPOLYMERIZATION SYSTEM, A MULTICOMPONENT INTERPOLYMER CAN ALSO BE OBTAINED IN WHICH THE INTERPOLYMER ESSENTIALLY HAS A STRUCTURE IN WHICH MONOMER UNITS FROM THE (A) GROUP ALWAYS ALTERNATE WITH MONOMER UNITS FROM THE (B) GROUP, EACH MONOMER UNIT FROM TE (A) GROUP BEING LINKED ONLY TO MONOMER UNIT FROM THE (B) GROUP AND EACH MONOMER UNIT FROM THE (B) GROUP BEING LINKED ONLY TO MONOMER UNITS FROM THE (A) GROUP. FURTHER THE PRESENT INVENTION CONCERNS THE APPLICATION OF SAID MULTICOMPONENT INTERPOLYMERS AND A METHOD FOR THE PRODUCTION THEREOF.
