Methacrylsäuremethylesterpolymer

摘要

A methyl methacrylate polymer comprises at least 50 weight % methyl methacrylate units and has a weight-average molecular weight of [the polymer is in the range from] 80,000 to 400,000, and the molecular weight between branching points calculated from the z-average molecular weight of the polymer is in the range from 30,000 to 1,000,000.
