Abstract

PURPOSE: To prepare a polyurethane elastomer having improved whiteness retention, and durability, by using a specific hindered piperidine derivative as part or all of the chain extender or terminator.
CONSTITUTION: A hindered amine compound of formula I: (R1 is H or benzyl group which may be substituted by halogen, lower alkyl, or lower alkoxy group; R2 is H, lower alkyl, phenyl group, halogen, etc.; X is hydroxyl, amino, monoalkylamino group, etc.; R8 and R9 may be the same or different, 1W3C alkyl group or saturated 5- or 6-membered ring) is used as part or all of the chain extender or terminator in preparing a polyurethane elastomer from a polymer glycol of molecular weight≥about 800, and an organic isocyanate.
