Aromatic polymers containing an element of the phosphorus family

Abstract

Abstract -O-M(-X)-O- NOVEL ESTERS OF A MEMBER OF THE PHOSPHORUS FAMILY AND A PHENOL-ALDEHYDE OF PHENOL-KETONE CONDENSATE ARE CHARACTERIZED IN THAT: (1) A MAJOR PROPORTION OF THE MOIETY OF THE MEMBER OF THE PHOSPHORUS FAMILY HAS THE FORMULA IN WHICH THE UNSATISFIED BONDS ARE ATTACHED TO ARYL NUCLEI OF THE SAME PHENOLIC CONDENSATE, AND IN WHICH M IS AN ATOM OF THE PHOSPHROUS FAMILY, AND N IS HALOGEN, HYDROXYL, MERCAPTO, HYDROCARBYL, HYDROCRBLOXY, HALOGEN-SUBSTITUTED HYDROCARBYL, HALOGEN-SUBSTITUTED HYDROCARBYLOXY, OR AN ARYLOXY RADICAL OF THE SAME PHENOLIC CONDENSATE TO WHICH M IS ATTACHED; (2) AT LEAST 60 PERCENT OF THE PHENOL-ALDEHYYDE OR PHENOLKETONE CONDENSATE HAS O,O''-ALKYLIDENE LINKAGES; AND (3) THE PHENOLIC CONDENSATE HAS AN AVERAGE NUMBER OF ARYL NUCLEI PER MOLECULE IN THE RANGE OF 3.5 TO 8. SUITABLE MEMBERS OF THE PHOSPHORUS FAMILY OF ELEMENTS ARE PHOSPHORUS, ARSENIC, ANTIMONY AND BISMUTH. THE THERMOPLASTIC PRODUCTS OF THE INVENTION CAN BE MODIFIED TO PRODUCE ADDITIONAL THERMOPLASTIC PRODUCTS SUCH AS REACTION PRODUCTS WITH AN OXYALKYLAION AGENT. THERMOSETTING PRODUCTS CAN BE PRODUCED BY CURING THE THERMOPLASTIC PRODUCTS OF THE INVENTION WITH AGENTS SUCH AS HEXAMETHYLENE TETRAMINE, OR OTHER DONORS OF METHYLENE RADICALS, OR POLYEPOXIDE, OR POLYSIOCYANATE, AND THE LIKE. THE PRODUCTS ARE USEFUL TO PRODUCE SHAPED ARTICLES SUCH AS MOLDED ARTICLES, LAMINATES, PROTECTIVE COATINGS, INCLUDING DRYNG OIL VARNISHES; ABRASIVE STRUCTURE; FRICTION ELEMENTS AND THE LIKE. OTHER USES ARE AS INHIBITORS AND STABILIZERS FOR POLYMERS, IN BASING CEMENTS AND AS FOUNDRY SAND BINDERS. THE POLYURETHANE DERIVATES CAN BE USED FOR THE PREPARATION OF FOAMED PRODUCTS, CASTINGS, COATINGS, AND THE LIKE. COMPOSITIONS OF THE INVENTION ARE ALSO USEFUL FOR THE TREATMENT OF NORMALLY COMBUSTIBLE CELLULOSIC MATERIALS TO RENDER THEM RETARDANT.
