Patent ID: 8084129

Claim:
A laminate comprising an interlayer sheet that is laminated to one or more film layers or rigid sheets, wherein the rigid sheet comprises a material having a modulus of about 690 MPa or greater (as measured by ASTM Method D638), the at least one interlayer sheet comprising a blend composition of ethylene copolymers that has a melt flow rate of less than 100 g/10 min, as determined in accordance with ASTM D1238 at 190° C. and 2.16 kg, and comprises: A. about 5 to about 95 wt % of an ethylene copolymer A, based on the total weight of the blend composition, wherein the ethylene copolymer A comprises copolymerized units of ethylene and about 3 to about 20 wt % of a comonomer selected from the group consisting of esters of C 4 -C 8 unsaturated acids having two carboxylic acid groups, anhydrides of C 4 -C 8 unsaturated acids having two carboxylic acid groups, and mixtures thereof, based on the total weight of the ethylene copolymer A; and B. about 5 to about 95 wt % of an ethylene copolymer B, based on the total weight of the blend composition, wherein ethylene copolymer B comprises copolymerized units of ethylene and about 6 to about 40 wt % of at least one polar monomer selected from the group consisting of vinyl acetate, alkyl acrylates, alkyl methacrylates, and mixtures of any two or more thereof, based on the total weight of the ethylene copolymer B, with the proviso that ethylene copolymer A and ethylene copolymer B are chemically distinct.
