Abstract: Method for coagulating an aqueous polymer dispersion, where the aqueous polymer dispersion comprises at least one polymer in dispersion in aqueous phase, and also comprises thermally expandable, thermoplastic microspheres, the polymer dispersion is coagulated by energy input, and the coagulated composition is delivered via an outlet aperture, preferably in the form of a nozzle.

Abstract: Described is a process for producing adhesive-coated articles, wherein an aqueous dispersion adhesive composition comprising a dispersed adhesive polymer and a dissolved polyvinylpyrrolidone is applied at high web speed to a film substrate using a coating machine having at least one rotating roller and wherein the coated film substrate may optionally be bonded to a further substrate. Also described is the use of polyvinylpyrrolidone as a defoamer for aqueous dispersion adhesive compositions applied to a film substrate using a coating machine having a rapidly rotating roller.
