摘要： Provided herein are glass laminates, preferably safety glass laminates, that comprise a polymeric interlayer sheet formed of an acid copolymer composition. The acid copolymer composition comprises an ethylene acid copolymer which, in turn, comprises copolymerized units of ethylene, about 5 to about 90 wt % of copolymerized units of a first α,β-unsaturated carboxylic acid having 3 to 10 carbon atoms; and optionally about 2 to about 40 wt % of copolymerized units of a derivative of a second α,β-unsaturated carboxylic acid having 3 to 10 carbon atoms. Optionally, a portion of the carboxylic acid groups of the copolymerized units of the ethylene acid copolymer are neutralized to form carboxylate salts. The acid copolymer composition also includes a hydroxyl-containing crosslinking agent and may also include an adjuvant. The glass laminates have superior resistance to creeping due to the properties of the acid copolymer composition, which may optionally be cross-linked.
