The invention relates to novel phosphinate polymers having the formula ##STR1## WHEREIN R is a phenylene or naphthylene group in which the O substituent is nonvicinal to the ##STR2## group, R' is an alkyl group of 1 to 15 carbon atoms or an aryl group of 6 to 15 carbon atoms, and n is from 5 to 50 units. The invention also relates to a process for the production of the novel polymeric phosphinate resins, and to combinations of such polymeric phosphinates with organic polymers such as polyesters, e.g., polyethylene terepthalate, and polyamides, e.g., hexamethylene adipamide. The combination of the present polymeric phosphinates with the organic polymers makes it possible to obtain flame retardant products, for example fibers suitable for carpeting and clothing.
