    摘要： This invention relates to high density polyethylene blown films having good barrier properties and improved processing characteristics. The method incorporates the use of peroxide which results in improved bubble stability without sacrifice in barrier properties. The polyethylenes have a density greater than about 0.950g/cc, are relatively narrow in molecular weight distribution MWD (in the range of from about 2.0 to about 6.5), and are of medium molecular weight. In an embodiment, the films also have a rheological breadth parameter, a, that has been reduced by at least about 5%, but not more than 45%, by addition of a peroxide to the polyethylene. The addition of peroxide improves processability without sacrificing strength and barrier properties such as oxygen transmission rate.

    摘要： The invention relates generally to the production of polyethylene, and particularly to the production of polyethylene that is mixed with peroxides during extrusion to increase the level of long-chain branching. In an aspect, the polyethylene is used for large part blow molding (LPBM) applications. In an embodiment, the cross-linked polyethylene has a density of from about 0.945 g/cc to about 0.965 g/cc, a molecular weight distribution (MWD) of at least from 10 to 25, for example, and a high load melt index (HLMI) (ASTM D1238 21.6 kg) of from about 1 dg/min to about 30 dg/min. In an embodiment, the cross-linked polyethylene is comprised of at least one olefin having an ESCR of 100 hours to 1000 hours, and a flexural modulus of 120,000 psi to 250,000 psi. ® KIPO & WIPO 2009

    摘要： PURPOSE: A method for preparing a thermoplastic elastomer composition is provided to reduce the fluctuation of the amount of supplied bulky rubber at an extruder despite the change of shape and volume of bulky rubber and to stably supply the bulky rubber. CONSTITUTION: A method for preparing a thermoplastic elastomer composition comprises the steps of supplying bulky rubber, a thermoplastic resin and additives to an extruder(2), melting and kneading the bulky rubber, thermoplastic resin and additives in the extruder, measuring the amount of the thermoplastic elastomer composition produced from the outlet of the extruder, calculating the amount of the bulky rubber by subtracting the amount of the thermoplastic resin and additives from the amount of the thermoplastic elastomer product, and controlling the supply amount of the bulky rubber based on the calculated amount of the bulky rubber.
