Abstract
L'invention a trait à la chimie des polymères. Elle concerne un procédé perfectionne de formation en solution de copolymères et terpolymères sensiblement dépourvus de gel d'isobutylène et d'un ou plusieurs diènes dont le poids moléculaire a une moyenne en nombre de valeur approximative inférieure à 500000, dont le pourcentage molaire d'insaturation a une valeur d'environ 8 à 45 et dont la dispersion de poids moléculaire a une valeur d'environ 3 à environ 30. L'invention concerne également les polymères obtenus par ce procédé.
