Abstract
A plug flow reactor having an inner shell 27 surrounded by outer shell 21 and having at least one annular flow passage 35 therebetween can be used to prepare compositions, including polymers. The plug flow reactor also includes inlet port 36, an outlet port 37 and a plurality of exchanger tubes 26 wherein the exchanger tubes are in fluid communication to the at least one annular flow passage. Polystyrene and high impact polystyrene can be prepared using the reactor.
Claims6
A process for preparing a polymer within a plug flow reactor, wherein the plug flow reactor comprises an inner shell and an outer shell having at least one annular flow passage therebetween, an inlet port and an outer port in fluid communication with the at least one annular flow passage, a plurality of heat exchanger tubes disposed within the inner shell, wherein the heat exchanger tubes are in fluid communication with the at least one annular flow passage and wherein the process comprises feeding reactants to the annular flow passage.
