DEFINITION

Classification: 523/433

Polymer derived from reactant containing element other than C, H, O, or N or chlorine-containing reactant of three or more carbon atoms:

(under subclass 427) Subject matter wherein the composition contains a polymer derived from a reactant containing an element other than C, H, O, N or other than a chlorine-containing reactant of less than three carbon atoms, e.g., chloroprene, polydiphenylsiloxanes, etc.
