In a process for preparing (meth)acrylic esters (E) of polyalkoxy-containing alcohols which comprises reacting polyalkoxy-containing alcohols (P) of formula (I) where

Preparation of (meth)acrylic esters of polyalkoxy-containing alcohols

Provided are processes for the production of (meth)acrylic esters of polyols, in which for 80 mol % or more of the esters, all of the OH groups of the polyols are esterified. Certain processes relate to reaction of polyols with acrylic acid and/or methacrylic acid in the presence of acidic esterification catalysts and in the presence of polymerization inhibitors, operating with reaction mixtures which are liquid at reaction temperature and are free from nonreacting solvents and/or azeotropic entrainers, the resultant water of condensation being stripped from the gas phase of the reaction space, and the (meth)acrylic acid is metered in three or more portions.

Process for preparing (meth)acrylic esters of polyols

The invention is a radiation curable coating composition containing epoxyacrylate formed by ring opening reaction between (meth)acrylic acid and a self-dispersing epoxy resin in an aqueous system.
