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.

Abstract: A tertiary N-vinylamide is polymerized, optionally together with further monomers, in the presence of an aliphatic hydrocarbon, at a temperature of from 0 DEG to 150 DEG C., using two types of initiator one of which is insoluble and the other soluble in the hydrocarbon used. The pulverulent or granular polymer obtained has a diminished content of residual monomer. It is suitable as protective colloid or dispersing agent for emulsion or suspension polymerizations.
