DEFINITION

Classification: 514/103

Phosphorus acid ester of polyhydric alcohol or

thioalcohol(e.g., P-X-R-X-P group, etc., wherein X is chalcogen and R is the residue of the polyhydric alcohol or thioalcohol):

(under subclass 102) Subject matter in which the organo-phosphorus compound is a phosphorus acid ester of a polyhydric alcohol or thioalcohol, e.g., P-X-(R) XP group, etc., wherein X is chalcogen and R is the residue of a polyhydric alcohol.
