Process for preparing Methyl Methacrylate Polymer.

摘要

A process for preparing a high-quality methyl methacrylate polymer by polymerizing a monomer comprising methyl methacrylate as a main component in the presence of a radical polymerization initiator and a chain transfer agent, said process comprising the step of adding a small amount of methanol as a solvent, and the step of carrying out the polymerization in a uniform solution at a temperature of 90 to 180 DEG C so that a monomer conversion may be in the range of 40 to 90 mol%. According to this process, the methyl methacrylate polymer can be obtained which reduces the generation of silver streaks, voids, coloring, odor and the like at the time of thermal molding. <IMAGE>
