Pyrrolidine-ring-containing compositions for use as anti-UV stabilizers in plastics materials |
摘要 |
For stabilizing polyolefin polymers such as polyethylene and polypropylene against the detrimental effects of exposure to UV-radiations and weathering agents, a stabilizing additive is disclosed which consist of a fatty acid ester of the N-(beta-hydroxyethyl)-2,2,3,4,5,5-hexamethylpyrrolidine. The lauric and palmitic acid esters are preferred.
