Latest Patents
Mac Leay's latest patents include a process for stabilizing polymer compositions against heat or light. This innovation involves N-(2,2,6,6-tetraalkyl-4-piperidinyl)amide-hydrazides of dicarboxylic acids, which contain both a light stabilizing group and a heat stabilizing group, along with a reactive hydrazide functionality in the same molecule. The reactive stabilizers are synthesized by reacting 4-amino-2,2,6,6-tetraalkylpiperidines with diesters or mono ester acid chlorides of dicarboxylic acids or dialkyl itaconates, followed by hydrazinolysis of the ester group of the intermediate mono esteramide. These compounds are beneficial for introducing permanent heat and light stability to coreactive polymers or copolymers. They also serve to stabilize inert polymeric systems against the degradative effects of heat and light when mixed with the polymers requiring stabilization.
