DEFINITION

Classification: 525/409

Solid polymer derived only from 1,2-epoxy reactants containing only C, H, and O:

(under subclass 403) Subject matter wherein the solid polymer

is derived from only 1,2-epoxy reactants which contain only carbon, hydrogen, and oxygen atoms (e.g., ethylene oxide-propylene oxide copolymer, ethylene oxide-glycidyl methacrylate copolymer, etc.).
