DEFINITION

Classification: 524/790

With reactive coupling agent:

(under subclass 789) Subject matter wherein the solid polymer or SICP is formed in the additional presence of a coupling agent which has sites reactive with both a portion of the elemental silicon, soil, or inorganic silicon compound DNRM and with the solid polymer, or SICP-forming system.
