Abstract
Disclosed is a composition which comprises or consists essentially of a high melt index ethylene acid copolymer comprising monomer units derived from ethylene, an alkyl (meth)acrylate, a (meth)acrylic acid, and an optional comonomer. Also disclosed is a composition comprising the ethylene acid copolymer crosslinked with a polyamine, a polyvalent metal salt, or combinations thereof. Also disclosed is a solution of the ethylene acid copolymer which can be used for solutions application to substrates.
Claims8
A composition comprising or produced from an ethylene acid copolymer and a curing agent wherein the acid copolymer has a melt index of greater than about 110 g/10 minutes;
- the acid copolymer comprises repeat units derived from ethylene, at least one alkyl (meth)acrylate, at least one acid comonomer, and optionally another comonomer;
- the acid comonomer includes (meth)acrylic acid, monoalkyl ester of 1,4-butene-dioic acid, or combinations thereof and the another comonomer includes maleic acid ester, maleic anhydride, or combinations thereof;
- the curing agent include poly[[6-(1,1,3,3-tetramethylbutyl)amino-s-triazine-2,4-diyl][(2,2,6,6-tetramethyl-4-piperidyl)imino]hexamethylene[(2,2,6,6-tetramethyl-4-piperidyl)imino]], an oligomeric polyamine including about 2 to about 100 amine groups, or combinations thereof.
