METHOD OF PREPARING BASE POLYMER SOLUTION FOR PRODUCING HALOBUTYL RUBBER Russian patent published in 2017 - IPC C08J3/11 C08F210/12 C08F6/24 

FIELD: chemistry.

SUBSTANCE: method is done by dissolving the moist crumb butyl rubber in hydrocarbon solvents by filing a moist crumb rubber, solvent, the filing and withdrawal solution base polymer and water output in the hollow device. While the device has a zone of mixing, dissolving and settling in which the dissolution of rubber crumb, the solution circulation of base polymer, which is at the top of the unit, in the lower part of the zone and the zone of dissolution is held. Ratio of mixing zones of dissolution and zone equal to 3-4:1. When the mixing zone consists of two sections with different diameters, with the ratio of height to diameter of the upper site is -1 0.8:1, and the lower sector 0.3 -0.5:1.

EFFECT: reducing losses and reaching base polymer averaging solution without spike concentration.
