The invention relates to a process for producing a copolymer based on methyl methacrylate, MMA, which consists of the block prepolymerization reaction and in which, in order to obtain transparent polymers with enhanced solvency resistance and good thermal stability, the monomer mixture further contains 0.15-2% by weight of monoethylene glycol dimethacrylate or allyl methacrylate. |
