FIELD: chemistry.
SUBSTANCE: invention relates to field of processing plastics, in particular to additive for processing polyolefins, which represents monoepoxyester of diane resin with molecular weight from 4000-4500 units and carboxylic acid - abietene, benzoic or salicylic. Obtained additive can be used as 100% product or in form of concentrate of said monoepoxyester in polyethylene with content of basic substance 10-20%.
EFFECT: increase of polyolefin melt index and 20-25°C reduction of processing temperature per each per cent of additive.
