DEFINITION

Classification: 525/102

Si-H or Si-C reactant contains an atom other than C, H, O, or Si bonded to a carbon atom:

(under subclass 100) Subject matter wherein the Si-H or Si-C bond-containing reactant or polymer thereof contains an atom other than C, H, or O bonded to carbon e.g., 3,3,3-trifluoromethyl propyl siloxane, etc.

(1) Note. Elements that are other than C, H, or O and are incorporated into the polymer by non Si-H a Si-C containing reactants are not considered for this subclass. The elements required must be part of a Si-H or Si-C reactant.
