The invention relates to a reactor and to a method for continuous polymerization, in which said reactor for the continuous production of polymers, particularly synthetic rubbers, contains at least one substantially tubular reactor housing (), wherein said reactor housing () has a drive shaft () that is connected to at least one agitator () arranged such that it can rotate inside the reactor housing (), and the agitator contains at least one, and preferably two, three or four helical mixing elements () which are designed to be preferably close to the wall or to come into contact with the wall.

The present invention relates to a process for the production of water and solvent-free hydrogenated nitrile rubber polymers, to the hydrogenated nitrile rubbers and the use thereof.

Process for the production of water and solvent-free hydrogenated nitrile rubbers

The present invention relates to specific water and solvent-free nitrile rubbers having specific functional groups and/or end groups, a process for the production thereof and the use thereof.

Process for the production of water and solvent-free nitrile rubbers

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 as well as a process for the production thereof. The invention further relates to a device suitable to accomplish said process.

Process for the production of water and solvent-free polymers

The invention relates to an energy efficient, environmentally favourable process for preparing water and solvent-free rubber ionomers and/or polymer nanocomposites comprising said rubber ionomers.

Process for the production of rubber ionomers and polymer nanocomposites

The present invention relates to specific water and solvent-free nitrile rubbers having specific functional groups and/or end groups, a process for the production thereof and the use thereof. This process involves removing volatile compounds from a fluid (F) containing (1) at least one nitrile rubber and (2) at least one volatile compound, wherein the process comprises at least the steps of a.) treating the fluid (F) in at least one conversation unit, b.) retreating the concentrated fluid from step a.) in at least one retreating unit and c.) feeding the retreated concentrated fluid from step b.) into at least one retreating unit.

The present invention relates to a reactor () and a process for continuous polymerization, where the reactor () has an essentially tubular reactor housing (). The reactor housing () has a drive () which runs along the geometric central axis () in the flow direction () and is configured as a central shaft. A rotatably arranged scraper or wiper () is provided within the reactor housing (); the scraper or wiper () has at least one scraper or wiper blade () to run along an interior side () of the reactor housing (). The rotational movement of the scraper or wiper () results in radial mixing of a stream within the reactor housing () which dominates gravity effects and, by virtue of shaping of the scrapers or wipers, optionally makes plug flow or a loop flow or backflow within the reactor () or else via an additional external pumped circulation system () possible. This allows the reaction conditions in the axial direction of the reactor housing () to be predicted and individually suitable reaction conditions to be set and controlled along the reactor housing, so that, in particular, a desired molecular weight distribution can be set.

The present invention relates to water and solvent-free polymers, in particular water and solvent-free synthetic rubber products like styrene butadiene rubber products and butadiene rubber products as well as a process for the production thereof. The invention further relates to a device suitable to accomplish said process.

The present invention relates to the industrial production of vinylene carbonate (VC) by elimination of hydrogen chloride from chloroethylene glycol carbonate (CGC) with tertiary amines in the absence of relatively large amounts of additional solvent.

Process for producing vinylene carbonate

The present invention relates to the industrial production of vinylene carbonate (VC) by eliminating hydrogen chloride from chloroethylene glycol carbonate (CGC) or solid catalysts in the gas phase, the reaction being carried out over a catalyst bed agitated by thorough mixing.

The present invention relates to the technical purification of vinylene carbonate (VC) by means of a simple thermal treatment with organic compounds which possess amidic nitrogen-hydrogen bonds, followed by a distillation and a melt crystallization. In this way VC of ultra-high purity is obtained. The high-purity vinylene carbonate can be stored and transported without stabilizer.
