Procedure

A stainless steel autoclave having a capacity of 20 liters and having baffles and Pfaudler stirring blades was supplied with a solution obtained by dissolving 2.5 g of a methyl methacrylate/acrylamide copolymer-based suspending agent (this was prepared according to the following method: a reactor was charged with 20 parts by weight of methyl methacrylate, 80 parts by weight of acrylamide, 0.3 part by weight of potassium persulfate and 1500 parts by weight of ion exchange water, and while the atmosphere in the reactor was replaced by nitrogen gas, the system was kept at 70° C.; the reaction was continued till the monomers were perfectly converted into a polymer, to obtain an aqueous solution of methyl acrylate/acrylamide copolymer; the obtained aqueous solution was used as the suspending agent), and the solution was stirred at 400 rpm, the atmosphere in the system being replaced by nitrogen gas. Then, 5000 g in total of the following monomer mixture was added while the reaction system was stirred, and the system was heated to 70° C. The moment when the internal temperature reached 70° C. was identified as the initiation of polymerization, and with this state kept for 180 minutes, the polymerization was terminated. Thereafter, the cooling of the reaction system and the separation, washing and drying of the polymer were performed according to ordinary methods, to obtain a copolymer (A) as beads. The polymerization percentage of the copolymer (A) was 98%, and the weight average molecular weight was 70000.
