发明人：D ALELIO GAETANO F
权利人:ALELIO GAETANO F D
摘要:This invention deals with new phosphorus containing polymeric esters having pendent groups therein of the formula OBTAINED BY THE REACTION OF A POLYMER HAVING AT LEAST 2 AND PREFERABLY AT LEAST 4 HYDROXY GROUPS THEREIN WITH A PHOSPHORUSHALOGEN COMPOUND OF THE FORMULA XP(O) (ORCX CXR'')2 wherein: R represents a divalent hydrocarbon radical containing 1-20 carbon atoms; R'' represents X, hydrogen or R''''; R'''' represents a monovalent hydrocarbon radical containing 1-20 carbon atoms; and X represents chlorine or bromine. Somewhat related polymers are also disclosed as derived by the reaction of WHEREIN Q'' is an organic moiety, n'' has a value of at least one, n'''' is one or two, R'''''' represents hydrogen or a monovalent hydrocarbon group of 1-20 carbon atoms, and the other symbols have the same meaning as defined above. Also disclosed are the reaction products of the phosphite compound HOP(ORCX CXR'')2 with an aldehyde and an organic nitrogen compound having one or two hydrogen atoms on the nitrogen, or with a compound having an ethylenic group therein. These new ester polymers and compounds are useful particularly as fire retardants, agricultural chemicals, fuel additives, plasticizers, monomers and intermediates for the synthesis of other useful derivatives.
