METHODS FOR REDUCING THE POLAR ADDITIVES NECESSARY FOR USE IN POLYOLEFINS.

摘要

The invention relates to a method for improving the effectiveness of polar additives used in polyolefins, in which an effective quantity of a coadditive compound having formula R1(OCH2CH2)XOH is incorporated into the polyolefin prior to the formation of the film, wherein R1 is a linear or branched alkyl chain with 20 to 100 carbon atoms and x varies between 2 and 100. The presence of these materials in polyolefin resins enables the use of a smaller quantity of polar additives without reducing the effectiveness thereof, as well as improving optical properties for films produced using said resins.
