METHOD OF INTRODUCING ADDITIVES INTO POLYMER Russian patent published in 2016 - IPC B29C67/00 B82B3/00 D01D5/247 

FIELD: chemistry.

SUBSTANCE: this invention relates to high molecular compounds. In the method of introducing additives into polymers, a polymer product of an oblong shape is drawn out of amorphous or semicrystalline oriented, non-oriented or partly oriented polymer in a direct aqueous emulsion of oil-in-water containing water in an extended phase and physically active liquid medium emulsified in water (the dispersed phase) which is not mixed with water at a temperature of drawing. Amount of physically active emulsified liquid medium must be not less than 2 %. Drawing is conducted at a deformation of not less than 2 %.

EFFECT: invention simplifies the method of introducing additives into the polymers and broadens the scope of application by spreading to the admixtures which are water-soluble but poorly or not soluble in water-based organic solvents.
