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.
