摘要： The present invention relates to a method for separation of a polymer from a polymer solution or dispersion, wherein (i) a solution or dispersion of a polymer in an organic solvent is atomized by being brought into contact with water vapor in an atomizer container; (ii) the mixture obtained in the atomizer container is routed into a polymer degasification container and flows through same, wherein the organic solvent present in the polymer particles is driven at least partially out of the polymer particles due to the thermal contact between the polymer particles and the water vapor and transitions into the gas phase (iii) the mixture exiting from the polymer degasification container is routed into a phase separator (1) and the organic solvent present in the gas phase is separated from the polymer particles and the condensed water vapor; and (iv) the polymer particles and the condensed water vapor are routed into a phase separator (2) in order to separate the polymer particles from the condensed water vapor.

摘要： The present invention is directed at a bulkpolymerisation process for the preparation of a polymer (P) comprising the steps of: (i) providing at least one diene monomer (DM) and optionally at least one comonomer (COM); (ii) contacting the at least one diene monomer (DM) and optionally the at least one comonomer (COM) with a catalyst system (CS) forming a reaction mixture (RM); (iii) polymerizing the reaction mixture (RM) comprising the at least one diene monomer (DM) and optionally the at least one comonomer (COM) in at least one reactor vessel (RV); (iv) isolating the polymer (P) obtained from the at least one reactor vessel (RV); wherein the reaction mixture (RM) comprises solvent, diluent and/or dispersant in an amount of ≤10 wt.-%, based on the weight of the reaction mixture (RM); and wherein the conversion rate of the diene monomer (DM) and optionally the comonomer (COM) is ≥80%.
