Abstract
Hydrophosphonylated derivatives of homopolymers and copolymers of poly allyl glycidyl ethers are formed by reacting said polymers with sodium hypophosphite (NaH.sub.2 PO.sub.2). The novel polymers of this invention may be represented by the general formula: ##STR1## wherein x ranges from about 5 to about 10.sup.6, y ranges from 0 to about 10.sup.6, A is interpolymerized units of one or more epoxides having the oxirane group ##STR2## and R is ##STR3## n is 0 to 19, and m is 0 to 20. y Preferably is zero, and x preferably ranges from about 5 to about 10.sup.6, and most preferably from 5 to 10.
