ABSTRACT:
A process is provided for reduction in the amount of free acrylate monomer from compositions consisting of or containing polyacrylate. The process involves addition to the composition of an alkanolamine or an alkanediolamine, preferably one of the ethanolamines, which scavenges the free acrylate monomer present into an inert form.
