摘要： Improving polyethylene film properties may be accomplished by measuring the specific energy input (SEI) to the extruder and then adjusting a process parameter in response to a change in the SEI and/or by introducing both a free radical initiator and an alkali earth metal stearate into the polymerization. Alternatively or in addition thereto, selecting the optimum free radical initiator for a particular polyethylene resin polymerized in the presence of a selected catalyst between two resin properties may be accomplished by examining the ratio of: % ⁢   ⁢ variation ⁢   ⁢ in ⁢   ⁢ a ⁢   ⁢ first ⁢   ⁢ property % ⁢   ⁢ variation ⁢   ⁢ in ⁢   ⁢ a ⁢   ⁢ second ⁢   ⁢ property of polyethylene resins individually made with each free radical initiator under consideration. The free radical initiator may be oxygen, peroxides, peroxyketals, peroxyesters, and/or dialkyl peroxides.

摘要： The rheology of polyethylene resin may be controlled by measuring the specific energy input (SEI) to the extruder and then adjusting a process parameter in response to a change in the SEI and/or by introducing both a free radical initiator and an alkali earth metal stearate into the polymerization. Indeed, the process parameter changed in response to the SEI measurement may be adjusting the proportion of free radical initiator, adjusting the proportion of alkali earth metal stearate, or both. The free radical initiator may be a peroxide, and the alkali earth metal stearate may be calcium stearate.

摘要： It has been discovered that the amount of fluoropolymer additive used in a polyethylene resin affects the quality of finish of an article made with free surface polyethylene resins using chromium, Ziegler-Natta or metallocene catalysts. Reducing the amount of fluoropolymer increases the matte nature of the polymer finish, whereas increasing the amount of fluoropolymer increases the gloss nature of the finish. Introducing a peroxide or air in an increasing amount increases the long chain branching (LCB) of the polymer. Introducing an antioxidant in an amount to balance the peroxide amount can improve the melt strength of the polymer, and the amount of antioxidant is balanced with the amount of peroxide and/or air. The resultant polymer density ranges between about 0.960 and 0.962 g/cm3 inclusive, where the molecular weight distribution (MWD) of the polymer is greater than 3 and less than 6.

摘要翻译： 已经发现，聚乙烯树脂中使用的含氟聚合物添加剂的量影响使用铬，齐格勒 - 纳塔或茂金属催化剂的用游离表面聚乙烯树脂制成的制品的表面光洁度。 减少含氟聚合物的量增加了聚合物涂饰的无光泽性质，而增加含氟聚合物的量增加了涂饰的光泽性质。 以增加的量引入过氧化物或空气增加聚合物的长链支化（LCB）。 引入抗氧化剂以达到平衡过氧化物量可以提高聚合物的熔体强度，并且抗氧化剂的量与过氧化物和/或空气的量平衡。 所得聚合物密度在约0.960至0.962g / cm 3之间，其中聚合物的分子量分布（MWD）大于3且小于6。
