| titleOfInvention | NEW PHOSPHONIC ACID ARYLESTER, A METHOD FOR THE PRODUCTION THEREOF AND THEIR USE FOR STABILIZING PLASTICS |
| abstract | New phosphonites (I) have formula (1) R1, when monovalent = Ph, or PhCH2 with 1-3 substits. alpha- methyl or alpha, alpha-dimethylbenzyl, naphthyl opt. with 1-5 substits. which are non aromatic hydrocarbon gp. 1-8C alkoxy or alkylthio, 6-10C aryl or aryloxy, or halogen of atomic no. 9-35 or, when divalent = phenylene opt. substd. by 1 or 2 1-8C non aromatic hydrocarbon gp. or naphthylene opt. substd. by 1 to 4 1-8C hydrocarbon gps. R2 = 1-18C nonaromatic hydrocarbon gp. 6-10C aryl, 6-10C aryl-methyl 6-10C aryl-ethyl or 6-10C aryl-isopropyl, R3 = H or R2, excluding cpds. where n = 1, R1 = Ph and R2= R3 tert, Bu or tert, octyl or alpha -dimethylbenzyl, or R2 = tert, Bu and R3 = H, or R2 = tert, octyl and R3 = Me. USE/ADVANTAGE - Alone or with phenolic antioxidants for stabilising plastics esp. polymerisation plastics (claimed) new and known (I) are obtd. readily, in high yield and purity. |
