Abstract
A continuous polymerization apparatus uses at least a first reactor and a second reactor (). Each of the reactors () includes at least one supply port (, and), an effluent port (), and a temperature detecting means (T, T), each of which detects the temperature in the reactor. The supply port () of the first reactor () is connected to supply sources () of a raw material monomer and a polymerization initiator, and the effluent port () is connected to the first supply port () of the second reactor () through a connection line (). The second supply port () of the second reactor () is connected to a replenishing line () that supplies a new raw material monomer to the second reactor.
