Acrylonitrile copolymers
Abstract
Abstract THE NOVEL COPOLYMERS CONTAIN ACRYLONITRILE (1-99 MOLES PERCENT) AND AN N-ARYLMALEIMIDE (99-1 MOLE PERCENT). THE COPOLYMERS MAY ALSO COMPRISE 25-90 MOLE PERCENT ACRYLONITRILE. FROM 1-25 MOLE PERCENT OF N-ARYL MALEIMIDE AND FROM 0-70 MOLE PERCENT OF AT LEAST ONE OTHER ETHYLNICALLY UNSATURATED MONOMOER COPOLYMERISABLE THEREWITH. WHEN THE OTHER MONOMER IS AN ALKENE OR DIENE, THE QUANTITY IS LIMITED TO THE RANGE FROM 0-50 MOLE PERCENT, AND WHERE THE OTHER MOMOMER IS AN AROMATIC OLEFIN THE MOLAR RATION OF AROMATIC OLEFIN TO ACRYLONITRILE LIES WITHIN THE RANGE 0.5-4, PREFERABLY 1-4. THE COPOLYMER IS PREPARED BY MIXING THE MONOMERS TOGETHER, PREFERABLY IN A LIQUID DILUENT AND POLYMERISING THE MIXTURE UNDER CONDITIONS OF FREE RADICAL CATALYSIS.
