NEW MATERIAL: The compounds of formula I [R 1 is 1-36C alkyl, 5-12C cycloalkyl, phenyl or the like; R 2 is either H or R 1 ; n is 1-4; when n is 1, T is either one of R 1 or formula II, T and R 2 form a ring together with C; When n is 2, T is 2-12C alkylene or the like; when n is 3, T is formula III or the like; when n is 4, formula IV (R 3 is H, 1-4C alkyl or the like; R 4 is H or methyl)]. n EXAMPLE: 2,2-bis[4-[3-(N-benzyl-N-hydroxylamino)-2- hydroxypropyl]oxyphenyl]propane. n USE: Stabilizer of synthetic polymers, which is effective in polypropylene composition containing phenolic oxidation inhibitor. n PROCESS: Hydroxylamine of formula V is allowed to react with epoxyde in a solvent such as ethanol in the presence of an inactive gas such as nitrogen gas at 20-100°C to obtain the compound of formula I. n COPYRIGHT: (C)1989,JPO |
