Hindered amine light stabilizer hydrazides for stabilizing polyurethane, polyurea and polyurethane-polyurea polymers |
| abstract |
HINDERED AMINE LIGHT STABILIZER HYDRAZIDES FOR POLYURETHANE STABILIZATION Abstract of the Disclosure Stabilized polyurethanes, polyureas and polyurethane-polyurea polymers having hindered amine light stabilizers (HALS) bonded thereto by means of a hydrazide functionality attached to the HALS are provided. The synergistic effect of a second amide functional group in the HALS-hydrazide provides improved photostabilization efficiency as compared to HALS-hydrazides of the prior art. |
