Energy-absorbing laminates for use in automobile windshields or other safety glass applications comprising a polycarbonate urethane and a sheet of glass are disclosed. The polyurethane is formed from a cycloaliphatic diisocyanate, a compound containing at least two active hydrogens per molecule and having a molecular weight below 250, and a polycarbonate diol prepared by the reaction of an aliphatic diol and a dialkyl carbonate using a titanium catalyst.
