Patent number: 5510429Abstract: A method of grafting alkyl (alkyl) acrylate to a polycarbonate at a carbon atom which both before and after grafting has an sp.sup.3 electron configuration, includes the step of contacting a polycarbonate which is in the solid phase with alkyl (alkyl)acrylate monomers in the presence of a suitable free radical initiator at a temperature sufficient to activate the free radical initiator for a time sufficient to attain a desired degree of grafting. The grafting method of the invention allows for the relatively rapid production of polycarbonate-graft-poly(alkyl(alkyl)acrylate) copolymers using conventional polycarbonate polymers which have not been specially modified to facilitate grafting. The resulting graft copolymer of the process generally has an alkyl (alkyl)acrylate content of from about 1 to about 20 percent by weight with the polycarbonate portion of the graft copolymer having a weight-average molecular weight of from about 5,000 to about 200,000.Type: GrantFiled: July 25, 1994Date of Patent: April 23, 1996Assignee: The University of AkronInventors: Sunggyu Lee, Ronald A.
