Abstract:
A molded article formed from a blend, the blend comprising: from 1 wt. % to 30 wt. % of a polypropylene; and from 60 wt. % to 99 wt. % of an ionomer formed from a partially neutralized precursor acid copolymer, wherein the precursor acid copolymer (a) comprises copolymerized units of ethylene and 5 wt. % to 30 wt. %, based on the total weight of the precursor acid copolymer, of copolymerized units of an ?,?-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms, and (b) has a melt index, I2, (according to ASTM D1238 at 190 C, 2.16 kg) of 10 g/10 min to 4,000 g/10 min, and wherein about 25% to about 65% of the acid groups derived from the ?,?-ethylenically unsaturated carboxylic acid of the precursor acid copolymer are neutralized.
