    Abstract: Copolymers of vinyl esters and crotonic acid are commonly prepared by polymerizing the monomers in bulk or in solution by means of a radical-forming initiator in the presence of a regulator. The polymers should be free from residual monomers and impurities as far as possible. This may be realized in that upon completion of the polymerization the unreacted monomers and other volatile impurities are removed from the reaction mixture by distillation. For this purpose, the use of an entrainer is advantageous. The copolymers are suitable as starting materials for adhesives and hair lacquers, hair setting lotions as well as hair sprays.
