ABSTRACT:
Laminated glass articles useful as automobile windshields or in other safety glass applications comprising a polyesterurethane and at least one sheet of glass are described. The polyesterurethane is a thermoplastic, transparent material that is formed preferably from an aliphatic polyester, e.g., poly(1,4-butylene adipate), a cycloaliphatic diisocyanate, e.g., 4,4'-methylene-bis (cyclohexyl isocyanate), and a monomeric aliphatic diol, e.g., 1,4-butane diol.
