Abstract

L'invention concerne un procédé de polymérisation ou de copolymérisation anionique de composés vinylaromatiques, tels que le styrène en solution avec une concentration initiale en monomères de 40 à 100 % en poids, dans des conditions non isothermes, de préférence dans un réacteur tubulaire ou à faisceau tubulaire qui est pourvu de moyens sur une section considérable. Ces moyens empêchent un transfert de chaleur avec l'environnement. On utilise, de préférence, comme solvant, du toluène, du méthylcyclohexane, de l'éthylbenzène ou du Dékalin, et la solution de polymère quittant la chambre de réaction est à une température d'au moins 170 °C. Un polymère styrène est produit avec une teneur en monomère inférieure à 50 ppm.
