(METH)ACRYLATE POLYMERS AND THE USE THEREOF AS POLYMER-BOUND UV INITIATORS OR ADDITIVE TO UV-CURABLE RESINS |
摘要 |
The invention relates to a (meth)acrylate polymer obtainable by polymerizing a mixture comprising a) 0.1% to 99.9% by weight of at least one (meth)acrylate of the general formula I in which the radicals R1-R6 and also m take on the definition indicated in the description; and b) 99.9% to 0.1% by weight of one or a plurality of ethylenically unsaturated monomers which are different from a) and which are copolymerizable with a), the components a) and b) together making up 100% by weight of the polymerizable constituents of the mixture, the MW of the polymer being situated in the range from greater than or equal to 1000 g/mol to less than or equal to 50 000 g/mol. The resulting polymers are preparable preferably by the route of suspension polymerization or bead polymerization and, preferably in solution in reactive diluent, serve as polymer-bonded photoinitiators or as an additive to UV-curable resins for a very wide variety of fields of application, particularly for printing inks. |
