APPARATUS FOR LIQUID-PHASE POLYMERISATION OF OLEFINS Russian patent published in 2012 - IPC B01J8/38 B01J19/18 B01J19/24 C08F10/00 

FIELD: process engineering.

SUBSTANCE: invention relates to liquid-phase polymerisation of one or more α-olefins in the presence of polymerisation catalyst. Proposed apparatus comprises first closed-loop reactor for pre-polymerisation of catalyst in fluid, or jacketed reactor with continuous mixing, at least, one second closed-loop reactor located downstream of flow for polymerisation, connection line for transfer of polymer suspension from said first reactor into said second reactor. Said connection line comprises: one or more adjacent pipelines arranged at gradually increasing heights. Every said pipeline and horizontal direction x makes angle α exceeding angle of rest of produced polymer. ''ON-OFF'' valve is arranged flush with the wall of said second reactor.

EFFECT: production of ethylene and propylene copolymers.
