Method for introducing imido alkylene substitution into aromatic carbo cyclic organic polymers
Abstract
Abstract A FRIEDEL-CRAFTS'' ALKYLATION METHOD IS PROVIDED FOR INTRODUCING IMIDO-ALKYLENE SUBSTIUTIONS, SUCH AS MALEIMIDO-METHYLENE-SUBSTITUTION, INTO A VARIETY OF ORGANIC POLYMERS HAVING CHEMICALLY-COMBINED AROMATIC CARBOCYCLIC ORGANIC RADICALS, AS PENDANT RADICALS ALONG THE POLYMER CHAIN, SUCH AS POLYSTYRENE, POLY(STYRENE-VINYLIC OR, DIENIC COPOLYMERS OR TERPOLYMERS) ETC. REACTION IS EFFECTED BETWEEN AN IMIDO-METHYLENE COMPOUND AND AN ORGANIC POLYMER HAVING CHEMICALLY-COMBINED AROMATIC CARBOXYCLIC ORGANIC RADICALS IN THE PRESENCE OF A FRIEDELCRAFTS'' CATALYST, SUCH AS BORON TRIFLUORIDE. THE IMIDOALKYLENE-SUBSTITUTED AROMATIC CARBOCYCLIC ORGANIC POLYMERS CAN BE EMPLOYED IN MAKING MOLDING COMPOUNDS, LAMINATES, VARNISHES, ETC.
