POLYMERISATION OF ISOOLEFIN WITH POLYMORPHOGENATES REGULATED WITH RESPECT TO POLYDISPERSITY Russian patent published in 2013 - IPC C08F210/12 C08F2/04 C08F2/12 

FIELD: chemistry.

SUBSTANCE: invention relates to method of polymerisation of monomers with obtaining isoolefin polymers and copolymers, polymerisation system for polymerisation of such monomers, catalytic system for carbocationic polymerisation of isoolefins, isoolefin polymer or copolymer, obtained by said method and with application of said catalytic system. Method of polymerisation of monomers with obtaining isoolefin polymers and copolymers includes polymerisation of one or more monomers in polymerisation medium, including one or more monomers, diluents and catalytic system. Diluent includes one or more halogenated hydrocarbons. Catalytic system includes one or more Lewis acids and multiple modifiers, which include one or more initiators and one or more polymorphogenates, which contain molecular oxygen or organic oxygenate. If polymorphogenate represents initiator, catalytic system includes second initiator. Regulation of concentration of said one or more polymorphogenates in said polymerisation medium is performed by regulated distribution of molecular mass (PMM) of isoolefin polymers and copolymers, constituting more than 2.0. Polymerisation medium is supplied in form of one or more raw material flows into reactor for polymerisation. Mixture of polymer and diluents is removed from reactor. Diluent is separated from mixture in order to separate polymer. Separated diluent is returned into one or more raw material flows, supplied into reactor. One or more polymorphogenates are added into at least one or more raw material flows.

EFFECT: providing novel polymerisation systems and processes with application of novel class of modifiers of catalytic systems-polymorphogenates.
