Patent number: 8598446Abstract: A safety laminate comprises an interlayer that comprises a crosslinkable blend of ethylene copolymers. The first ethylene copolymer comprises copolymerized units of ethylene, optionally a first olefin having the formula CH2?C(R1)CO2R2, and a second olefin having the formula CH2?C(R3)COOH. The first ethylene copolymer is optionally at least partially neutralized. The second ethylene copolymer consists essentially of copolymerized units of ethylene, optionally a first olefin having the formula CH2?C(R1)CO2R2, and a third olefin having the formula CH2?C(R4)D. R1, R3 and R4 represent hydrogen or an alkyl group; R2 represents an alkyl group; and D represents a moiety containing an epoxy group. The crosslinkable blend is useful as an interlayer in safety laminates. Methods for preparing the safety laminates are also provided.Type: GrantFiled: July 29, 2011Date of Patent: December 3, 2013Assignee: E I du Pont de Nemours and CompanyInventors: George Wyatt Prejean, Sam Louis Samuels, Alison Margaret Anne Bennett
