ABSTRACT:
An improved process for the preparation of an alkyl vinyl ether/maleic anhydride copolymer in which copolymerization is carried out in an admixture of an ester and an hydrocarbon.
The alkyl vinyl ether/maleic anhydride copolymer obtained by this process does not contain any harmful aromatic solvent such as benzene, etc. In addition, the alkyl vinyl ether/maleic anhydride copolymer has a higher apparent bulk density than can be obtained in prior processes.
