Abstract

PURPOSE: To obtain a modified polyurethane useful as a material for paints, lacquers, elastic fibers, etc., by stabilizing the polymer against light by introducing a specified piperidine derivative into the polymer molecule.
CONSTITUTION: A piperidine derivative represented by formula I, wherein R1 R2 are each H, an oxygen free radical or an alkyl group, R3 is a C2WC10 alkylene and n1 and n2 are each 0W about 50, is prepared, for example, by reacting a 2,2,6,6,-tetramethyl-4-piperidone derivative with dipentaerythritol, and then reacting the product with a C2WC10 alkylene oxide. Next, the modified polyurethane of the purpose, containing a group represented by formula II in the polymer molecule, is prepared by reacting a hydroxyl group-terminated polyether-polyol and/or a polyester-polyol with a polyisocyanate in the presence of the compound of formula I.
