摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
