Process for preparing methyl methacrylate polymer |
摘要 |
A process is provided 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, a chain transfer agent, and 5 to less than 10 wt. % methanol. The polymerization is carried out in a uniform solution. According to this process, a methyl methacrylate polymer is obtained which reduces the generation of silver streaks, voids, coloring, odor and the like at the time of thermal molding.
