Abstract
Abstract A thermoplastic ionic polymer composition composed of 10 to 90 weight percent of a soft segment ionic polymer and 90 to 10 weight percent of a hard segment ionic polymer reacted with at least 10% to 100% of a metal ion based on the amount of free acid in said composition.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
51 words
A thermoplastic ionic polymer composition composed of 10 to 90 weight percent of a soft segment ionic polymer and 90 to 10 weight percent of a hard segment ionic polymer reacted with at least 10% to 100% of a metal ion based on the amount of free acid in said composition.
Claim 2
Dependent Claim
51 words
A thermoplastic ionic polymer composition composed of 10 to 90 weight percent of a soft segment ionic polymer and 90 to 10 weight percent of a hard segment ionic polymer reacted with at least 10% to 100% of a metal ion based on the amount of free acid in said composition.
Claim 3
Dependent Claim
71 words
The composition of claim 1 wherein the soft segment ionic polymer is a copolymer of an acidic monomer and a diolefin of 4 to 10 carbon atoms and the hard segment ionic polymer is a copolymer of an acidic monomer and an aromatic α-olefin, said acidic monomer being selected from the class consisting of acrylic acid, methacrylic, combinations thereof and each of said monomers combined with itaconic acid or itaconic anhydride.
Claim 4
Dependent Claim
21 words
The composition of claim 1 wherein the acidic monomer comprises at least 10% of each of the components of the blend.
Claim 5
Dependent Claim
13 words
The composition of claim 1 wherein the metal ion is barium or magnesium.
Claim 6
Dependent Claim
24 words
The composition of claim 3 wherein the acidic monomer is added incrementally to a polymerization system to incorporate said acidic monomer into the polymer.
