ABSTRACT:
The present invention relates to a novel process for the production of low viscosity copolymers of maleic acid monoalkyl ester and vinyl alkyl ethers characterized in that the copolymerization of alkyl vinyl ether is performed with a mixture composed of maleic acid anhydride and maleic acid monoalkyl ester. The specific viscosity is controlled by the setting of a certain maleic acid anhydride to maleic acid monoalkyl ester ratio.
