DEFINITION

Classification: 106/287.13

C bonded directly to Si atom:

(under subclass 287.1) Coating or plastic compositions which contain silicon bonded directly to carbon.

(1) Note. When a substituent is claimed as a monovalent radical and is otherwise unidentifiable, placement is proper in subclass 287.13.

(2) Note. A composition containing "a silicone" or "silicone oil" otherwise unidentifiable is classified here.
