    摘要： The present invention provides a composition comprising a blend of:
    (A) from about 90 to about 10 % by weight of polymethylpentene, wherein the polymethylpentene has a molecular weight between from about 200,000 to about 700,000, and a melt flow rate between from about 20 grams/10 minutes to about 200 grams/10 minutes; (B) from about 10 to about 90 % by weight of polypropylene, wherein the polypropylene has a molecular weight between from about 150,000 to about 350,000, and a melt flow rate between from about 1 gram/10 minutes to about 10 grams/10 minutes;    whereby the blend of (A) and (B) has improved elongation and improved release properties. The invention further provides a blend with improved tensile strength, improved elongation, and improved release properties, and a method of producing a article with improved release properties from the blend.
