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 polymerization section and a purification section, wherein the product from the polymerization section is subjected in the purification section to a sequence of purification steps comprising: removal of the vapor phase from the product from the polymerization section by means of flash separation to obtain a first vapor phase and a polymerization product; subjecting the first vapor phase to a compression and condensation treatment to obtain a second vapor 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 polymerization process.
