PURPOSE:To obtain the subject composition having extremely excellent physical properties and high industrial value by compounding syndiotactic poly-4- methylpentene-1 to a base resin. CONSTITUTION:The objective composition can be produced by mixing (A) 0.0001-10 pts.wt. of syndiotactic poly-4-methylpentene-1 with (B) 99.9999-90 pts.wt. of a highly crystalline polypropylene. The component A to be used in the present process has a melting point of >=160 deg.C and is produced by using a catalyst system composed of an aluminoxane and a transition metal compound such as isopropyl(cyclopentadienyl-1-fluorenyl)hafnium dichloride. |
