DEFINITION

Classification: 528/10

(under subclass 1) Subject matter under Class 520, ..., involving polymer products derived from a silicon-containing reactant wherein at least one atom of silicon is bonded directly to an atom of hydrogen or carbon or processes of polymerizing; polymerizable compositions containing as a reactant a compound of silicon wherein a silicon atom is directly bonded to a hydrogen or carbon atom or processes of preparing.

SEE OR SEARCH THIS CLASS, SUBCLASS:

480+, for processes of preparing a polymer not involving a chemical modification of the polymer, by the addition of a material thereto, and for chemically modifying material other than the polymer. Subclasses 480+ also provide for processes of admixing with a broadly claimed nonreactant material.
