Abstract
A system for production of a polymer that may include a first high shear mixing device configured for producing a nanodispersion comprising particles or bubbles having a mean diameter less than 1 micron dispersed in a monomer-containing liquid or gaseous phase; a pump configured for delivering a pressurized liquid stream comprising the monomer to the first high shear mixing device; and a vessel configured for receiving the nanodispersion and for maintaining a predetermined pressure and temperature.
Claims20
A system for production of a polymer, the system comprising:
- a first high shear mixing device configured for producing a nanodispersion comprising particles or bubbles having a mean diameter less than 1 micron dispersed in a monomer-containing liquid or gaseous phase;
- a pump configured for delivering a pressurized liquid stream comprising the monomer to the first high shear mixing device;
- and
- a vessel configured for receiving the nanodispersion and for maintaining a predetermined pressure and temperature.
A system for production of a polymer, the system comprising:
- at least one high shear mixing device configured for producing a nanodispersion comprising particles or bubbles having a mean diameter less than 1 micron, the at least one high shear mixing device comprising at least one rotor and at least one stator separated by a shear gap, and wherein the high shear mixing device is configured to produce a tip speed at a tip of the at least one rotor of greater than 22.9 m/s (4,500 ft/min);
- a pump configured for delivering a pressurized liquid stream to the at least one high shear mixing device;
- and
- a vessel configured for receiving the nanodispersion from the at least one high shear mixing device.
A system for production of a polymer, the system comprising:
- at least one high shear mixing device comprising a rotor-stator set having a rotor tip, wherein the device is configured for operating at a flow rate of at least 300 L/h and at a tip speed of at least 22.9 m/sec, and wherein the device produces a nanodispersion comprising particles or bubbles having a mean diameter less than 1 micron dispersed in a monomer-containing liquid or gaseous phase;
- a pump configured for delivering a pressurized liquid stream comprising the monomer to the high shear mixing device;
- and
- a vessel configured for receiving the nanodispersion from the high shear mixing device and for maintaining a predetermined pressure and temperature.
