POLYOLEFIN MASTERBATCHES AND FILMS

摘要

Polyolefin compositions can be improved by blending an additive composition into the polyolefin composition. The additive composition comprises a hydrocarbon resin, the resin having a molecular weight lower than that of the polyolefin in which it is blended. The additive composition further comprises a high performance nucleating agent for increasing the crystallization temperature of modified polyolefin composition in comparison to a modified polyolefin composition in which the nucleating agent is absent.
