Abstract (en)
[origin: WO2017102675A1] The invention relates to a method for producing hydroxybenzophenone polyglycol ether (meth)acrylate comprising the steps of (i) reacting hydroxybenzophenone with ethylene carbonate to obtain hydroxybenzophenone monoglycol ether, (ii) ethoxylating hydroxybenzophenone monoglycol ether with ethylene oxide to obtain hydroxybenzophenone polyglycol ether, and (iii) transesterifying hydroxybenzophenone polyglycol ether with alkyl (meth)acrylate to obtain hydroxybenzophenone polyglycol ether (meth)acrylate.
