Abstract:
A bi-modal composition comprising a thermoplastic composition that is melt processible consisting essentially of (a) E/X/Y copolymers where E is ethylene, X is derived from 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/V 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) 5-60 wt. % based on (a)+(b) of one or more E/(M)AA copolymers having 3-25 wt. % (M)AA or salts thereof, wherein the E/X/Y copolymers have an Mw in the range of 80,000 to 500,000, and the E/(M)AA copolymers have an MW between 2,000 and 30,000 and (c) 5-50 wt. % based on (a)+(b) of one or more aliphatic, mono-functional organic acids having fewer than 30 carbon atoms or salt thereof, wherein greater than 80% of all the acid of (a) and of (b) and of (c) is neutralized.
