Abstract
The present invention relates to a process for producing a polyacrylate resin having a residual acrylate monomer content of <0.1% by weight, based on resin solids, by preparing an initial polyacrylate resin and subsequently polymerizing this initial polyacrylate resin in the presence of a monomer having a low vapor pressure, such as maleic anhydride, and a peroxide initiator to reduce the monomer content.
