Title: Continuous reactor capable of controlling degree of polymerization of polymer and control method thereof
Inventor: KONOO YUTAKA
IPC: C08G63/78
Filed: 1991-11-08
Abstract: PURPOSE:To provide a continuous reactor capable of controlling the degree of polymerization of a polymer by measuring the viscosity of the polymer flowing out from the reactor, controlling the rate of outflow and adjusting the residence time of monomers or oligomers in the reactor. CONSTITUTION:A continuous reactor equipped with a viscometer and an outflow- controlling unit on the midway of the outlet pipe and capable of controlling the degree of polymerization of the polymer. The viscosity of the polymer flowing out is constantly measured by the viscometer attached on the midway of the outlet pipe. If the viscosity of the polymer flowing out is higher than a desired value, the outflow of the polymer is increased by the outflow-controlling unit attached on the midway of the outlet pipe so as to reduce the residence time of the monomers or the oligomers in the reactor. If the viscosity of the polymer flowing out is lower than the desired value, the outflow of the polymer is reduced by the outflow-controlling unit so as to increase the residence time of the monomers or the oligomers in the reactor. By this continuous reactor, the degree of polymerization of the polymer can be constantly and suitably controlled and kept to a suitable state and the quality of the produced polymer can be kept uniform.
