[0157] Analytical method

[0158] Water Content of Fluid F: The sample was placed in a centrifuge and spun at 4000 rpm for 5 minutes at room temperature. Water was then collected at the bottom of the vial and weighed.

[0159] Total Volatile Concentration: Rubber samples were cut into 2x 2mm pieces. About 30 g of rubber flakes were placed in an alumina crucible. Determine the weight of the crucible and rubber. The crucible containing the rubber sample was then placed in a vacuum furnace at a temperature of 105°C and a vacuum of 130 hPa for 60 minutes. After drying, the crucible was placed in a desiccator and allowed to cool for 30 minutes. The crucible is then weighed again. Determine weight loss.

[0160] Residual solvent concentration in product P: The residual solvent concentration of this product was determined by headspace gas chromatography. A weighed portion of the sample (0.5+-0.005 g) was placed in a headspace bottle and a measured amount of solvent (1,2 dichlo...

example 1

[0178] A sample of Fluid (A) was placed in the stirred vessel and stirred at 58°C for 10 minutes. The stirrer was then stopped and the sample was left to settle. After 30 minutes the organic phase was separated from the aqueous phase and the residual water content was measured in a centrifuge. The residual amount of water was 35 vol%.

example 2

[0180] 160ml of fluid (A) was placed in the container and 240ml of water was added. The mixture was stirred at 58°C for 10 minutes. The stirrer was then stopped and the mixture was left to settle. After 30 minutes the organic phase was separated from the aqueous phase and the residual water content was measured in a centrifuge. The residual amount of water in the organic phase was 10.0 vol%.

Abstract

The invention relates to a production device for water- and solvent-free polymers, which includes at least one concentration unit. The concentration unit includes: a heater (2) connected to a degassing container (4), whereby the degassing container (4) The bottom of the degassing container (4) is connected to the pump (4.2), and the upper part of the degassing container (4) is connected to at least one steam pipeline (4.1); a heating unit (6), which is connected to the pump (4.2) of the concentration unit and the extruder. The feed points (12) on the extruder unit are connected; an extruder unit includes at least one feed point (12), an extruder degassing section (16), and an accumulation section. (20) and an outlet section (22) whereby the extruder degassing section (16) further includes at least one vent (15) connected to the vapor line (15.1).

Description

[0001] The present invention is a divisional application of the parent application with the application number 200980139308.1, the filing date is September 17, 2009, and the title of the invention is "Method for producing polymer without water and solvent". technical field [0002] The present invention relates to water- and solvent-free polymers, in particular water- and solvent-free synthetic rubber products, like non-halogenated and halogenated butyl rubber products, and processes for their production. The invention further relates to a device suitable for carrying out said method. Background technique [0003] Synthetic rubbers have important industrial uses and are typically produced by (co)polymerization of monomers, typically via slurry, solution or dissolution processes. Examples of synthetic rubbers include butyl and halobutyl rubbers, polyisobutylene, ethylene propylene diene M-type rubbers (EPDM), nitrile butadiene rubbers (NBR), and styrene-butadiene rubbers (SBR...
