DEFINITION

Classification: 522/132

Solid polymer treated contains halogen:

(under subclass 131) Subject matter wherein the solid polymer reacted with elemental halogen contains at least one halogen atom.

(1) Note. The solid polymer may have been derived from a halogen containing monomer or may have been treated with a halogen containing material so as to introduce halogen atoms therein prior to the reaction with elemental halogen.
