METHOD FOR THE CONTINUOUS PRODUCTION OF AN AQUEOUS POLY(METH)ACRYLATE RESIN DISPERSION

摘要

A method for the production of an aqueous poly(meth)acryIate resin dispersion comprises the steps of: I) providing a (meth)acrylate polymer and/or a (meth)acrylate copolymer with an acid group content of >= 0.1 mmol to <= 200 mmol per 100 g of polymer at a temperature of >= 50 °C to <= 170 °C; II) adding a neutralizing agent to the (meth)acrylate polymer and or (meth)acrylate copolymer to yield an at least partially neutralized (meth)acrylate polymer and/or (meth)acrylate copolymer; III) adding water to the at least partially neutralized (meth)acrylate polymer and/or (meth)acrylate copolymer to yield a composition comprising the at least partially neutralized (meth)acrylate polymer and/or (meth)acrylate copolymer and water; and IV) mixing the composition of step III) to yield a dispersion of particles of the at least partially neutralized (meth)acrylate polymer and/or (meth)acrylate copolymer in water At least step III) is conducted as a continuous step.
