Abstract

DC60 (08/10/41) This invention involves a continuous process and a unique polymerization system by separate injection of the Catalysts and feed additives made-up And mixtures of polyethylene inter-polymer Which has a distinctive feature that is distributed Broad molecular weight (MWD) and mixture consistency. Fitting Methods for making such mixtures and the substances from which they are made. From the above mixtures This new mixture contains The unique characteristics that Melting flow ratio, I10 / I2 from 8 to 30, Mw / Mn greater than 4, as determined by the chromas. Gel permeability tography, melting index, from 0.01 to 1000 g / 10 min, preferable is more than 0.1 g / 10 min, more preferable from 0.1 to 10 g / 10 min, density less than 0.945 g / Cubic centimeter And when mounted on the base The total weight of the crystallized polymer portion, percent by weight, at most covered vertices temperatures in excess of 75 ° C, as determined by the separation. Analysis part sequence The crystallization in the range of 20 to 100 degrees Celsius is equal to or greater than the mathematical product. 1.7946x10-28x10 (31.829x mixture density) for mixture density in grams / cubic centimeter. This new mix shows good machinability and improved toughness properties. Especially durability Resistant to tears and bumps Excellent and suitable film material - especially good for application applications such as the high-performance bin liner. And bags used for heavy-duty transport. The invention involves continuous processing and polymerization systems. Characterized by a separate injection of Catalysts and feed additives made-up And mixtures of poly Ethylene interpolymer Which has a distinctive feature that is distributed Broad molecular weight (MWD) and mixture consistency. Fitting Procedures for the preparation of the mixture and the substances made from it. This new mixture contains The unique characteristics that Melting flow ratio, I10 / I2 from 8 to 30, Mw / Mn greater than 4, as determined by the chromas. Tografie gel permeability Melting index, from 0.01 to 1000 g / 10 min. Popular is more than 0.1 g / 10 min. Preferred is from 0.1 to 10 g / 10 min. Density is less than 0.945 g / cm3. And when mounted on the base Total weight of the crystallized polymer portion,% by weight, at most covered peak temperatures in excess of 75 ° as determined by using analytical separation The crystallization in the range of 20 to 100 degrees is equal to or greater than the result. Mathematical multiplication is 1.7946x10-2x10 (31.829x mixture thickness) for compound density. In grams / cubic centimeter This new mix shows good machinability and improved toughness properties. Especially durability Excellent and optimum film resistance and impact resistance - especially good for applications such as high-performance bin liners. And bags used to transport heavy loads
