Abstract:
1. A process for manufacturing a methacrylate (co)polymer comprising conducting polymerization while feeding a monomer (mixture) containing at least 90 wt % in total of at least one methacrylate monomer and a radical polymerization initiator represented by formula (II) into a reactor and for an average residence time of 2 to 6 hours, where an initiator concentration and a polymerization temperature satisfy a relationship represented by equations (1) to (4) and the polymerization temperature is not less than 110° C. and not more than 160° C.; wherein A is an initiator concentration (a molar ratio of the initiator/the monomer); B is a polymerization temperature (° K); and ln is a symbol for a natural logarithm; wherein R is alkyl or fluoroalkyl.
