Abstract
A prepolymer syrup is produced by (A) continuously supplying a monomer comprising methyl methacrylate as a main component and a radical-polymerization initiator to a reaction zone wherein substantially complete mixing is achieved, during which the reaction zone is kept under such conditions that the concentration of remaining initiator is from 1/2 to 1/1,000 times that of the initiator supplied, or (A') continuously supplying the said monomer to a first reaction area in a reaction zone wherein at least two reaction areas, in which substantially complete mixing is achieved, are arranged in series, continuously supplying a radical-polymerization initiator simultaneously to at least two reaction areas including the first one, and passing the monomer through the reaction areas successively thereby polymerizing the monomer into syrup, during which the reaction areas are kept under such conditions that the concentration of remaining initiator in at least the reaction areas to which the initiator is supplied is from 1/2 to 1,000 times that of the initiator supplied and then, optionally in the case of (A'), (B) introducing the resulting reaction mixture into a reaction zone wherein piston flow is achieved, and passing it though the zone during which the temperature thereof and the average residence time of the mixture are maintained so that the final syrup is produced in the zone and the concentration of remaining initiator is reduced to a negligible amount, the polydispersity of the polymer in the syrup being 3.0 or less (i.e. the ratio of weight average D,P. to number average D.P.).
