DEFINITION

Classification: 524/859

Silicate containing compound as sole Si-containing reactant, e.g., ortho silicate esters, etc.:

(under subclass 858) Subject matter wherein all silicon-containing reactants contain at least one -O--O- structure.

(1) Note. Included are, e.g., ortho silicate esters, etc.

(2) Note. Silicate structure in siloxane material is conventionally depicted as SiO[supscrpt]4/2[end supscrpt] to indicate four-shared oxygens.
