METHOD OF OBTAINING POLYMETHYLMETHACRYLATE Russian patent published in 2010 - IPC C08F120/14 B01J31/22 

FIELD: chemistry.

SUBSTANCE: described is a method of obtaining polymethylmethacrylate via radical polymerisation in a methylmethacrylate mass in the presence of an initiating system, one of the components of which is benzoyl peroxide. The method is distinguished by that, the second component of the initiating system used is bis-ferrocenylborate macrobicyclic tris-1,2-cyclohexanedionedioxymate of iron (II), molar ratio bis-ferrocenylborate macrobicyclic tris-1,2-cyclohexanedionedioxymate of iron (II): benzoyl peroxide equals (0.01-0.1):(0.05-1) and polymerisation is carried out at 30-60°C.

EFFECT: faster polymerisation, reduced consumption of components of the initiating system, lower polymerisation temperature, elimination of the gel effect, regulation of molecular weight of the obtained polymethylmethacrylate.
