METHOD AND DEVICE FOR HALOGENATION OF ELASTOMERS Russian patent published in 2001 - IPC

Abstract RU 2170237 C2

FIELD: manufacture halogenized butyl rubbers and devices for continuous halogenation of elastomer solutions. SUBSTANCE: method consists in forming and maintaining continuous stable state of emulsion of solution of polymer being halogenized with halogen; gas-and-liquid mixture formed in device is periodically separated in hollow attachment into communicating flows: peripheral flow and axial flow which are periodically combined between attachments in porous separating layers and are finally combined after last attachment in way of flow motion. Invention contains also description of device for halogenation of elastomers. EFFECT: possibility of performing continuous halogenation of elastomers obtaining homogeneous finished product. 3 cl, 2 dwg, 1 tbl, 6 ex
