ABSTRACT:
Process for the preparation of copolymers of definite specific viscosities from hydantoin vinyl ethers of the formula I and olefinically unsaturated compounds by free-radical polymerization of the monomers in a solvent mixture consisting of cyclohexane and toluene, it being possible to vary the specific viscosity of the copolymers within wide limits by altering the ratio of the two solvents. The meaning of the individual symbols can be seen in patent claim 1.
