摘要:
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.

摘要:
A molded article comprises an ionomer composition and has improved optical properties. The ionomer composition comprises an ionomer that is produced by partially neutralizing a precursor acid copolymer ant that has a melt index of about 400 g/10 min or less. The precursor acid copolymer comprises copolymerized units of an a-olefin having 2 to 10 carbons and, based on the total weight of the precursor acid copolymer, about 19.5 to about 30 wt % of copolymerized units of an α,β-ethylenically unsaturated carboxylic acid having 3 to 8 carbons.
摘要:
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 α,β-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.
