METHOD OF INTRODUCING ADDITIVES INTO POLYMERS Russian patent published in 2009 - IPC C08L39/00 D06P7/00 

FIELD: chemistry.

SUBSTANCE: method involves drawing out a polymer object in an adsorption-active medium, containing a dissolved additive, and drying the polymer. The polymer used is amorphous or amorphous-crystalline, oriented, non-oriented or partially oriented polymer. Drawing is carried out with deformation value of not less than 2%. The adsorption-active medium used is a liquid which is immiscible with water at temperature for drawing out the polymer. Before drying, the polymer is further drawn out, with deformation value of not less than 2% in an aqueous solution containing a dissolved additive.

EFFECT: invention simplifies the known method and widens its field of use through distribution to amorphous, oriented or partially oriented polymers, and to introduced additives, which are soluble in water, but poorly or completely insoluble in organic solvents which are immiscible with water.
