ABSTRACT OF THE DISCLOSURE Polyester/polyether segmented copolymers are stabilized against degradation by UV light via copolymeriza- tion with novel diesters and/or bis-hydroxyalkyl terminated derivatives of 2,2,6,6-tetramethylpiperidines. These stabilized copolymers also possess good processability charac- teristics. The introduction of the above derivatives into the backbone of polyester/polyether copolymer chain increases the photostability of the copolymerized product and increases the durability of these stabilizers toward further processing, such as dyeing and finishing, and toward normal use operations such as washing. Copolymerization also minimizes any toxological effects which might arise from the use of the piperidine derived stabilizer additives. Preparation of certain additives is also disclosed.
