Abstract

See full text

A continuous polymerization apparatus uses at least a first reactor and a second reactor (10, 20). Each of the reactors (10, 20) includes at least one supply port (11a, 21a, and 21b), an effluent port (11b, 21d), and a temperature detecting means (T1, T2), each of which detects the temperature in the reactor. The supply port (11a) of the first reactor (10) is connected to supply sources (1, 3) of a raw material monomer and a polymerization initiator, and the effluent port (11b) is connected to the first supply port (21a) of the second reactor (20) through a connection line (15a). The second supply port (21b) of the second reactor (20) is connected to a replenishing line (15b) that supplies a new raw material monomer to the second reactor.
