ACRYLATE POLYMERS AND USE THEREOF AS POLYMER-BOUND UV INITIATORS OR AS ADDITIVE TO UV-CURABLE RESINS Russian patent published in 2015 - IPC C08F220/30 C08F220/18 C09D133/14 C08F2/48 C08F4/00 

FIELD: chemistry.

SUBSTANCE: present invention relates to (meth)acrylate polymer, which is obtained by polymerising a mixture comprising a) 0.1 to 99.9 wt % of at least one (meth)acrylate of general formula where residues R¹-R⁶ and m assume values given in the description, and b) 99.9 to 0.1 wt % of one or more ethylenically unsaturated monomers which are different from (a) and are compolymerisable with (a), wherein components (a) and (b) constitute 100 wt % of the polymerisable components of the mixture, wherein M_W of the polymer ranges from ≥1000 to ≤50000 g/mol. The formed polymers can be used as UV initiators for polymerisation reactions used in printing ink.

EFFECT: obtaining (meth)acrylate polymers which can be used as polymer initiators or ink additives.
