摘要： Syndiotactic polypropylene blends having a unique set of mechanical properties may be prepared by blending syndiotactic polypropylene with a high molecular weight mineral oil, an ultra low density polyethylene, or both. The syndiotactic polypropylene blends of the present invention have been found to have reduced flexural modulus, reduced haze, improved impact strength and shorter injection molding cycle times. It has been determined that the addition of about 5 to about 10 percent high molecular weight mineral oil to a syndiotactic polypropylene can decrease flexural modulus values by about 25 to about 30 percent. Moreover, the addition of up to about 10 percent mineral oil to the syndiotactic polypropylene material does not show signs of bleeding or impair clarity, in fact, percent haze values are slightly improved with the addition of mineral oil. Additionally, injection molding cycle time optimization shows an improvement of about 12 seconds in overall cycle time utilizing a syndiotactic polypropylene blend with 5% mineral oil in comparison to a syndiotactic polypropylene without mineral oil. The syndiotactic polypropylene blends according to the present invention may be further processed according to accepted practices to make cast films, blown films, injection molded parts, blow molded containers, and other articles using basic plastics fabrication techniques as known in the art.

摘要： A polyethylene may be prepared using a mixture of a silica supported catalyst and a magnesium chloride supported catalyst. By changing the ratio of the two catalysts, the polyethylene produced may have a varying bulk density and shear response. The method allows for the tuning or targeting of properties to fit a specific application, such as a blow molding or vapor barrier film.

摘要： It has been discovered that the properties of sheet or film materials or structures can be improved by co-extruding a rubber-impact modified heterophasic copolymer core layer with at least a second polyolefin. The second polyolefin may be a Ziegler-Natta catalyzed polyethylene (ZN PE), Ziegler-Natta catalyzed polypropylene random copolymer (ZN PP RCP), a metallocene catalyzed polypropylene random copolymer (mPP RCP), a linear low density polyethylene (LLDPE) and/or a metallocene catalyzed medium density polyethylene (mMDPE). Improvements include, but are not necessarily limited to, reduced haze and increased gloss. These sheet or film materials may be co-extruded with other resins or laminated with other materials after extrusion.
