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: A process for the production of an elastomer agglomerate composition wherein the process comprises the steps in this order: (a) providing a slurry comprising elastomeric particles having an average particle size of ≤150 nm in water; and (b) forcing the slurry from (a) through an aperture at a flow velocity of at least 500 m/s. The elastomer agglomerate compositions produced via such process demonstrate a particularly desirable high average particle size.

Abstract: The present invention relates to a process for the production of a polymer using a compound comprising at least 2 unsaturated carbon-carbon bonds, wherein the process comprises a polymerisation section and a purification section, wherein the product from the polymerisation section is subjected in the purification section to a sequence of purification steps comprising: ⋅removal of the vapour phase from the product from the polymerisation section by means of flash separation to obtain a first vapour phase and a polymerisation product; ⋅subjecting the first vapour phase to a compression and condensation treatment to obtain a second vapour phase and a condensed monomer phase; wherein the purification steps are conducted in this order. Such process allows for the optimal utilisation of raw materials in the polymerisation process.
