Abstract

PURPOSE: To prepare methacrylate resin polymer plates, by polymerizing a polymerizable liquid composition, wherein a polymerization initiator is dissolved in a prepolymer methyl methacrylate syrup, in the space between the moving bands.
CONSTITUTION: A polymerization initiator, e.g. azobisisobutyronitrile, etc. is dissolved in a syrup, which is obtained by preliminary polymerization of methyl methacrylate type monomers, and has a conversion of 20W40wt.%, a number-average molecular weightx1≥500, a weight-average molecular weightx2≤2,500, a ratio x2 x1≤2.5, and a viscosity of 1W200 poises, to form a polymerizable liquid composition. The composition thus obtained is fed from one end of the space between the moving bands 1 and 2, which are quided by supports 7, rolls 8, etc., travel facing each other, and is passed through the hot water polymerization zones A to D at about 60W90°C and the heat-treating zones E and F at about 110W150°C under heating, then the polymer plate formed is taken out of the other end continuously
