METHOD OF OBTAINING POLYMETHYLMETHACRYLATE Russian patent published in 2009 - IPC C08F20/18 C08F4/00 

Abstract RU 2348655 C1

FIELD: chemistry.

SUBSTANCE: invention concerns methods of obtaining high-molecular compounds by method of 'live' radical polymerisation. Invention claims application of complex ruthenium compound with carborane fragment as catalyst, tert-butylamine as activation agent, and carbon tetrachloride as activation agent. Process speed is accelerated by 10-20 times in comparison to the prototype.

EFFECT: accelerated process of obtaining fine-dispersion polymethylmethacrylate by the method of controlled radical polymerisation.
