DEFINITION

Classification: 524/863

Poly (di organo siloxane) reactant has at least one SiO other than as Si-O-Si, e.g., Si-O-C, or SiOH group, etc.:

(under subclass 860) Subject matter wherein said poly(di organo siloxane) reactant has at least one Si-O-A linkage where A is an atom other than Si.

(1) Note. Included are, e.g., Si-O-C, Si-OH, etc.; these are the so-called hydrolyzable groups.
