5,5-Bis(perfluoroalkylheteromethyl)-2-hydroxy-2-oxo-1,3,2-dio xaphosphorinanes, derived acyclic phosphorus and phosphoric acids obtained by ring-opening, and salts or esters thereof are prepared from heteroatom containing perfluoroalkyl terminated neopentyl glycols of the formula HO[CH2C(CH2-X-E n-R p)2CH2O]H by cyclization with appropriate phosphorus containing esters or acids, or hydrolysis. These compositions provide improved thermal stability, and useful low surface energy oil and water repellent coatings for textiles, glass, paper, leather and other materials. Another aspect of this invention relates to the use of the phosphite group containing products as polymer stabilizers.
