POLY(4-METHYL-1-PENTENE) PROCESSING STABILITY AND UV STABILITY

摘要

32776CA An additive composition for increasing processing stability and/ or UV stability of polymers of 4-methyl-1-pentene which consists essentially of an effective amount of at least one hindered amine and at least one phosphite compound wherein the ratio of said hindered amine to said phosphite is in the range of about .1 to about 10: about .1 to about 10. Optionally, one or more hindered phenols may also be present.
