DEFINITION

Classification: 524/755

Ether compound DNRM, e.g., aryl ether, dimethylether, etc.:

(under subclass 700) Subject matter wherein a compound having at least one C-O-C linkage where neither carbon is doubly bonded to chalcogen, e.g., as illustrated below, or CH3-O-CH3, etc., is present as DNRM during formation of a solid polymer or SICP. [figure]
