METHOD OF OBTAINING TRIBLOCKCOPOLYMERS OF METHACRYLIC MONOMERS Russian patent published in 2014 - IPC C08F293/00 C08F4/42 

FIELD: chemistry.

SUBSTANCE: method includes successive radical polymerisation of three monomers in presence of catalyst, whereas catalyst applied is complex compound of ruthenium with carborane fragment, initiator, whereas initiator applied is carbon tetrachloride, and activator. As monomers methylmethacrylate, isoboronylmethacrylate and tret-butylmethacrylate are applied. As activator isopropylamine is applied, and as catalyst 3,3-{[1',1'-diphenyl-6'-phenyl-6'-(6',8-µ-(o-phenylene))]-1',6'-diphosphohexane}-3-chlorine-closo-3,1,2-dicarbollylruthenium is applied.

EFFECT: obtaining copolymers of required composition with low polydispersity with application of lower catalyst concentrations.
