Abstract
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 CH═C(R)COR, and a second olefin having the formula CH═C(R)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 CH═C(R)COR, and a third olefin having the formula CH═C(R)D. R, Rand Rrepresent hydrogen or an alkyl group; Rrepresents 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.
