MOLDED ARTICLES COMPRISING IONOMER COMPOSITIONS

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 a,ß-ethylenically unsaturated carboxylic acid having 3 to 8 carbons.
