DEFINITION

Classification: 522/99

Processes involving a polysiloxane having ethylenic unsaturation as reactant or as solid polymer; or compositions therefore:

(under subclass 1) Subject matter involving treating a group containing material having ethylenic unsaturation so as to form a solid polymer therefrom; or chemically modifying a solid polymer derived from a C C Si-O-S reactant containing ethylenic unsaturation; or chemically modifying a solid polymer with a C C Si-O-Si reactant containing ethylenic unsaturation; or composition therefore, and C is a carbon of an organic radical.

(1) Note. This subclass provides for compositions for use in processes provided for herein.

(2) Note. See Class 520, Glossary, for a definition of the term "ethylenically unsaturated".
