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.
