FIELD: polymer materials.
SUBSTANCE: invention relates to preparation of cellular polymer particles suited to be used in coating deposition compositions. Cellular polyesters-based polymer particle according to invention including spherical particles having numerous air hollows and long-chain aliphatic groups and/or spatially hindered branched-chain hydrophobic groups associated with surface of said spherical particles is proposed. A composition for preparing indicated cellular particles and a method of preparing the same are developed.
EFFECT: enlarged assortment of starting materials for polymeric coating compositions.
