PHOSPHITADDITIVE IN POLYOLEFINEN

摘要

The whiteness and stability of a polyolefin have been found to be improved upon addition of a first phosphite, an arylalkyl diphosphite, and a second phosphite selected from the group consisting of a second arylalkyl diphosphite and a triarylphosphite. In addition, the addition of a triarylphosphite with an arylalkyl diphosphite has as been found to improve the hygroscopic nature and the hydrolytic stability of the arylalkyl diphosphite.
