DEFINITION

Classification: 525/193

Agent contains an ethylenic group:

(under subclass 192) Subject matter wherein the treating agent is ethylenically unsaturated.

(1) Note. Included herein are polymers which were obtained only from ethylenic reactants as treating agents.

SEE OR SEARCH THIS CLASS, SUBCLASS:

70+, for a polymeric mixture containing a graft copolymer derived from ethylenic reactants only; or for a process or product obtained by treating an ethylenic reactant which reacts with the polymer and which resultant product is admixed with an additional solid polymer.

88+, for a polymeric mixture containing a block copolymer derived from ethylenic reactants only or for a process or product obtained by treating a mixture of polymers having functional terminal ends or with a coupling agent and subsequently contacting said product with an additional solid polymer.
