STABILIZER FOR SYNTHETIC RESINS

摘要

Compounds represented by the general formula

wherein A represents an alkylene group having 1 to 4 carbon atoms and n is an integer of 1, 3 or 4; when n = 1, R represents an alkyl group having 1 to 20 carbon atoms; when n = 3, R represents a group of formula

and when n = 4, R represents a group of formula


Their use, alone or in combination with known thioether-type antioxydants, as heat- and oxidation stabilizers for synthetic resins, particularly for polyolefins.
