PURPOSE:To provide titled composition capable of increasing resistance to oxidative deterioration by its bonding to polymer sensitive to such deterioration, consisting mainly of a compound of specific formula obtained by the reaction between isophorone diisocyanate and phenolic compound of specified formula. CONSTITUTION:The objective composition consisting mainly of a compound of formula II (A is isophorone diisocyanate residue; B is phenolic compound residue; n is 0-3), which can be obtained by dissolving in a solvent (e.g. N,N- dimethyl acetamide). (A) isophorone diisocyanate and (B) a phenolic compound of formula I (R1 is t-butyl, sec-butyl or neopentyl) [e.g., 1,3,5-tris(4-t-butyl-3-hydroxy- 2,6-dimethylbenzyl)isocyanuric acid] followed by reaction.
