Abstract:
A process for manufacturing a shaped article from a polyolefin composition nucleated with a combination of at least one dicarboxylic acid and at least one aliphatic monocarboxylic acid selected from the group consisting of oleic acid, stearic acid, behenic acid, myristic acid, abietic acid, lauric acid, linoleic acid, ricinoleic acid, dihydroxystearic acid, arachidic acid, eicosenoic acid, erucic acid, tetracosenoic acid, elaidic acid and mixtures thereof, comprising the steps of:primarily processing said polyolefin composition by melting and resolidification of the polymer to form a starting material for a secondary processing step; and secondarily processing said starting material into a shaped article by a process that excludes melting and resolidification.
