Abstract: The present invention is a polymeric resin composition having improved toughness, suitable for use in transparent glazing, comprising an at least partially neutralized ethylene acid copolymer metal carboxylate resin, wherein the metal carboxylate consists essentially of zinc metal counter-ions.

Abstract: The invention describes a polymeric sheet that has at least one layer that comprises an ionomer or ionomer blend that incorporates a partially neutralized alpha, beta-ethylenically unsaturated carboxylic acid component and is useful in glass laminate applications. The ionomer or ionomer blend contains one or more monovalent metal ions in an amount ranging from about 1 to about 60%, preferably about 10 to about 55%, and more preferably about 15 to about 50%, and one or more polyvalent metal ions in an amount ranging from about 40 to about 99%, preferably about 45 to about 90%, and more preferably about 50 to about 85%. This ratio range of monovalent and polyvalent metal neutralization ions provides synergistically greater adhesion to glass than found for either the monovalent or the polyvalent metal neutralization ions alone.

Abstract: The present invention is an improved polymeric resin composition comprising or consisting essentially of from about 70 wt % to about 79 wt % units derived from ethylene and from about 21 wt % to about 30 wt % units derived from an ?,?-unsaturated carboxylic acid having from 3 to 8 carbons. Resins of the present invention are particularly suitable for preparing transparent laminates useful as glazing elements that provide a greater measure of safety than non-laminated glazing elements. Laminates of the present invention have 3% haze or less without the addition of amines.
