DEFINITION

Classification: 8/557

Acid polymer, e.g., carboxylated or sulfonated polymer:

(under subclass 552) Subject matter wherein the polymeric additive is an acid polymer.

(1) Note. Generally, acidic polymers are, e.g., polymers with pendant or terminal COOH, SO3H, or SO4H P04H radicals, etc., or polymers noted as being acid polymers.
