FIELD: chemistry.
SUBSTANCE: said additive is an acetylated glycerine ester of a fatty acid, which is effective in reducing coefficient of friction of a moulded object. The invention also relates to an object moulded from polyethyleneterephtalate, such as a container and method of improving packing efficiency of perfom for bottles into a container.
EFFECT: reduced polymer yellowing and coefficient of friction to 0,66 in a 25 s cycle.
