Abstract
A polymer composition comprises a polyethylene polymer having a Melt Relaxation Index of 2 or greater and a salt of a branched alkyl phosphonic acid. A polyethylene film having improved barrier to water vapor and oxygen comprises a high-density polyethylene polymer having a density of about 930 kg/m3 to about 980 kg/m3 and a Melt Relaxation Index of 2 or greater and a salt of a branched alkyl phosphonic acid.
Claims18
A polymer composition comprising:
- (a) a polyethylene polymer composition having a Melt Relaxation Index of 2 or greater;
- and
- (b) a salt of a branched alkyl phosphonic acid, wherein the branched alkyl phosphonic acid comprises a branched alkyl group selected from the group consisting of tert-butyl, tert-pentyl, and neopentyl.
A polyethylene film comprising (i) a high-density polyethylene polymer composition having a density of about 930 kg/m3 to about 980 kg/m3 and a Melt Relaxation Index of 2 or greater and (ii) a salt of a branched alkyl phosphonic acid, wherein the branched alkyl phosphonic acid comprises a branched alkyl group selected from the group consisting of tert-butyl, tert-pentyl, and neopentyl.
