Abstract
A continuous polymerization apparatus uses at least a first reactor and a second reactor (). Each of the reactors () comprises a supply port () and an effluent port (). 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 () thereof is connected to the supply port () of the second reactor () by a connection line (). The connection line () is combined with a replenishing line () through an injection valve () at a combining part. The injection valve () comprises, in a full closure state thereof, a clearance that may cause a fluid comprising at least the raw material monomer to flow from the replenishing line () to the connection line ().
