Abstract:
A composition comprising a thermoplastic composition that is melt processible consisting essentially of (a) E/X/Y copolymers where B is ethylene, X is a C3 to C8 &agr;,&bgr; ethylenically unsaturated carboxylic acid, and Y is a softening comonomer selected from the group consisting of alkyl acrylates and alkyl methacrylates wherein the alkyl groups have from 1-8 carbon atoms, or ionomers of the E/X/Y copolymers wherein X is about 2-30 wt. % of the E/X/Y copolymer, and Y is 0 to about 35 wt. % of the E/X/Y copolymer, and (b) 5-50 wt. % based on (a)+(b) of one or more E/(M)AA copolymers having 3-25 wt. % (M)AA or salts thereof, wherein the acid of (a) and of (b) is neutralized to greater than 40%, wherein the E/X/Y copolymers have the weight average molecular weight (Mw) in the range of 80,000 to 300,000, and the E/(M)AA copolymers having the Mw between 2,000 and 30,000 and wherein (M)AA is shorthand notation for â€œ(meth) acrylic acidâ€  which is in turn shorthand notation for â€œmethacrylic acid and/or acrylic acidâ€ .
