Abstract RU 2711504 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing an aqueous suspension containing a plurality of polyisobutylene particles suspended therein, as well as polyisobutylene products containing polyisobutylene or formed therefrom. Method includes at least the following stages: A) reacting an organic medium comprising i) polyisobutylene and ii) an organic diluent with an aqueous medium containing at least one LCST compound having a turbidity temperature of from 0 to 100 °C, and B) removing at least a portion of the organic diluent to obtain an aqueous suspension containing polyisobutylene particles. Particles of polyisobutylene have size of 0.05 mm to 25 mm.

EFFECT: method according to the invention enables to obtain polyisobutylene in aqueous media, having reduced or low tendency to agglomeration.
