ABSTRACT:
New ethylene/acid copolymer ionomers which contain both (meth)acrylic acid and certain dicarboxylic acid monomers are described. The polymers may be melt processed as readily as ethylene/(meth)acrylic acid dipolymer ionomers, in contrast to ethylene/acid copolymer ionomers containing only dicarboxylic acid monomer derived in-chain acid units. Polymers with typical levels of (meth)acrylic acid and low levels of diacid provide ionomers comparable to existing ionomers, but which have adhesive and polymer blend compatibilizing characteristics, while polymers with higher levels of diacid will exhibit properties which depend on in-chain diacid derived units.
