PREPARATION OF SEMI-CRYSTALLINE THERMOPLASTIC POLYMERS

摘要

The present invention relates to a plastic composition having improved crystallization temperature (Tc) and reduced spherulitic size and hence improved transparency characteristics which comprises a polymer selected from aliphatic polyolefins (PO) and copolymers containing at least one aliphatic olefin and one or more ethylenically unsaturated aliphatic comonomers and an imide alone or in combination with aliphatic fatty acids or its salts in an amount sufficient to improve crystallization temperature, reduce spherulitic size and hence improve transparency.
