Abstract: Disclosed herein is a core-shell graft copolymer produced by coagulation of an aqueous latex comprising a quantity of particles of the copolymer and a quantity of a fatty acid surfactant, wherein the coagulation involves the addition of a quantity of a multivalent metal salt, preferably a bivalent or trivalent metal salt. Such copolymer provides in an improvement of the surface properties of moulded articles produced from such copolymers, as demonstrated by a reduction of the content of gels in the surface layer.

Abstract: The invention relates to a process for the production of an elastomer agglomerate composition, comprising: forcing a slurry through an aperture in a valve assembly (1) to obtain the elastomer agglomerate composition; wherein the valve assembly (1) comprises the valve (2) and a seat (3) that are arranged opposite each other to provide a flow channel for the slurry to be homogenized with an emulsifying channel section (5) that is provided with the aperture; wherein the emulsifying flow channel section is arranged at an angle (a) with respect to an axial center line of the valve in a cross sectional view of the valve assembly; and wherein the slurry comprises elastomeric particles in water.
