FIELD: chemistry.
SUBSTANCE: invention relates to a method of obtaining particles with a defined average diameter based on a thermoplastic polymer and powder. A molten mixture of thermoplastic material P with an additive A is prepared. The additive A contains a portion which is compatible with the thermoplastic material P and a portion which is incompatible with the thermoplastic material P and insoluble therein. The mixture is cooled and then treated with a compound B for layering. The compound B has a structure which is compatible with part of the structure of additive A. The weight ratio of components of the mixture is calculated using the formula: (weight of additive A + weight of compound B)/(weight of additive A + weight of compound B + weight of material P) and ranges from 0.01 to 0.6.
EFFECT: method enables to obtain particles with controlled geometry and given size.
