Process for the production of high molecular weight polymersnMaleic anhydride and alkyl vinyl ethers by radicalnSolution polymerization of maleic anhydride and alkyl vinyl ethers,nwherein the polymerization in the presence of 5 ton100 wt .-%, based on the sum of the newly to be polymerizednMonomers, a prepolymerized maleic anhydride / alkyl vinyl ether copolymer,nwith a molecular weight of 100,000nto 10 million daltons, the alkyl radicals being carried outnof the alkyl vinyl ether each have 1 to 8 carbon atoms. |
