ABSTRACT:
A method for the separation of technical methanol-methyl methacrylate mixtures by polymerization of the methyl methacrylate, wherein the polymerization is suitably carried out as a copolymerization, at least with long-chain aliphatic C.sub.8 to C.sub.20 -alkyl esters of methacrylic acid as comonomers, and as a solution polymerization, and the methanol can be recovered by distilling it off.
