Zusammenfassung:Disclosed laminates particularly useful as safety glazings comprising a polymeric interlayer sheet, wherein the polymeric interlayer sheet comprises a blend composition of an ethylene copolymer A and an ethylene copolymer B, which has a melt flow rate of less than 100g/10 min, as determined in accordance with ASTM D1238 at 190° C. and 2.16 kg, and wherein the ethylene copolymer A comprises copolymerized units of ethylene and about 3 to about 20 wt % of an ester or anhydride of a C4-C8 unsaturated acid having two carboxylic acid groups and the ethylene copolymer B comprises copolymerized units of ethylene and about 6 to about 40 wt % of a polar monomer selected from the group consisting of vinyl acetate, alkyl(meth)acrylates, and mixtures thereof.
