DEFINITION

Classification: 524/576

Adding nonreactive material to chemically modified solid polymer:

(under subclass 570) Subject matter wherein the solid polymer derived from at least one hydrocarbon monomer is chemically modified prior to admixing of the nonreactant material therewith.

(1) Note. It is not necessary for this subclass that a positive process step of chemically modifying the polymer be claimed. It is sufficient if the polymer has been chemically reacted (e.g., halogenated polymer, sulfonated polymer, etc.) prior to the admixing step.
