Claims17
A polyoxyalkyleneamine modified sulfonated block copolymer comprising:
- a. at least one sulfonated block copolymer comprising at least two polymer end blocks A and at least one polymer interior block B, wherein
- each A block contains essentially no sulfonic acid or sulfonate ester functional groups and each B block is a polymer block containing from about 10 to about 100 mol % sulfonic acid or sulfonate ester functional groups based on the number of sulfonation susceptible monomer units of the B block;
- and
- b. at least one polyoxyalkyleneamine in an amount of from about 0.6 to 2 mol-equivalent of amine groups per mol sulfonic acid or sulfonate ester functional groups of the sulfonated block copolymer.

A coated article comprising a substrate and a coating composition comprising:
- a. at least one sulfonated block copolymer comprising at least two polymer end blocks A and at least one polymer interior block B, wherein
- each A block contains essentially no sulfonic acid or sulfonate ester functional groups and each B block is a polymer block containing from about 10 to about 100 mol % sulfonic acid or sulfonate ester functional groups based on the number of sulfonation susceptible monomer units of the B block;
- and
- b. at least one polyoxyalkyleneamine in an amount of from about 0.6 to 2 mol-equivalent of amine groups per mol sulfonic acid or sulfonate ester functional groups of the sulfonated block copolymer.
