Method for making imido-substituted aromatic polymers
Abstract
Abstract A FRIEDEL-CRAFTS'' ALKYLATION METHOD IS PROVIDED FOR INTRODUCING IMIDO-ALKYLENE SUBSTITUTION, SUCH AS MALEIMIDOMETHYLENE-SUBSTITUTION, INTO A VARIETY OF ORGANIC POLYMERS HAVING CHEMICALLY-COMBINED AROMATIC CARBOCYCLIC ORGANIC RADICATS, EITHER IN THE POLYMER BACKBONE SUCH AS POLYARYLENESULFONES, POLYARYLENEOXIDES, POLYARYLENECARBONATES, POLYARYLENE ESTERS, POLYPHENYLENE, ETC., OR 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 CARBOCYCLIC ORGANIC RADICALS IN THE PRESENCE OF A FRIEDEL-CRAFTS'' CATALYST, SUCH AS BORON TRIFLUORIDE. THE IMIDO-ALKYLENE-SUBSTITUTED AROMATIC CARBOCYCLIC ORGANIC POLYMERS CAN BE EMPLOYED IN MAKING MOLDING COMPOUNDS, LAMINATES, VARNISHES, ETC.
