METHOD FOR OBTAINING NUCK-DISPERSED BULK SOLIDS OF STYRENE AND α-METYLSTYRENE USING CATION EMULATORS Russian patent published in 2018 - IPC C08J3/12 C08J3/11 

FIELD: technological processes; chemistry.

SUBSTANCE: invention relates to the field of high molecular compositions, namely to a process for producing a styrene copolymer bulk solid α-methylstyrene, comprising the preparation of a solution of a styrene copolymer with αmethylstyrene in chloroform, adding to the resulting solution an aqueous solution of cationic surfactant to obtain an emulsion, then it is mixing and dispersing, removing the chloroform on a rotary evaporator, boiling-down of water to obtain a bulk solid and its washing with water followed by drying, while as the cationic surfactant Catamine AB is used.

EFFECT: provision of finely dispersed styrene copolymer bulk solids with α-methylstyrene, and an improvement in its dielectric properties, a decrease in the value of tangent angle of dielectric loss.
