Abstract
A telomer of styrene and maleic anhydride of molecular weight less than 2500 is produced by polymerizing the monomers in benzene or benzene substituted by at least one methyl group, e.g. xylene, as solvent at 160-270 DEG C. in the presence of a free radical forming catalyst, e.g. di-tert.-butyl peroxide or cumene hydroperoxide. The polymerization may be carried out under superatmospheric pressure using a molar ratio of styrene to maleic anhydride of 1:2 to 2:1.
