  • Polymerization reactor and polymerization process
    Patent number: 5456888
    Abstract: A continuous static polymerization reactor for the production of liquid polymers comprises an elongated hollow reaction chamber (30) which has a porous wall (31) and a jacket means (40) spaced around the reaction chamber (30), which is provided with means (44) for introducing a fluid through the porous wall (31). The reactor is particularly useful for a process for making liquid polymers by condensing monomers and/or oligomers. It comprising the use of a pressurized gas to cause the reaction mixture to reach a foam consistency. This is beneficial in the condensation polymerization. Feeding a fluid through the porous wall into the reaction chamber avoids build up of the polymer on the wall.
    Type: Grant
    Filed: November 16, 1993
    Date of Patent: October 10, 1995
    Assignee: Dow Corning S.A.

The reactor is particularly useful for a process for making liquid polymers by condensing monomers and/or oligomers. It comprising the use of a pressurized gas to cause the reaction mixture to reach a foam-like consistency. This is beneficial in the condensation polymerization. Feeding a fluid through the porous wall into the reaction chamber avoids build up of the polymer on the wall.
