Stabilization of polyolefins.

摘要

In thermal stabilization of poly( alpha -olefin) fibers, such as a melt spun polypropylene, in which the poly( alpha -olefin) contains a hindered phenol, an organic phosphite, a hindered amine, and a metal salt of a fatty acid, the further inclusion of an alkali metal phosphate, such as sodium phosphate, results in improved thermal stability of the finished fiber.
