METHOD FOR THE REDUCTION OF POLAR ADDITIVES REQUIRED FOR USE IN POLYOLEFINS

摘要

A method for improving the efficacy of polar additives used in polyolefins is disclosed. The method is related to the addition of an effective amount of a co-additive compound of the formula R1(OCH2CH2)xOH to the polyolefin prior to forming the film, wherein R1 is a straight or branched chain alkyl of 20 to 100 carbon atoms and x is 2 to 100. The presence of these materials in polyolefin resins allows less polar additives to be used without losing their efficacy and also leads to improved optical properties for films made from such resins.
