Abstract

L'invention décrit des copolymères dérivant d'au moins deux monomères organiques cycliques et qui présentent certaines caractéristiques réglees. Les copolymères dérivent de monomères organiques pouvant subir une polymérisation d'addition avec ouverture de cycles en présence d'un amorceur contenant H actif. Ces copolymères présentent un rapport prédéterminé entre les OH terminaux primaires et les OH terminaux secondaires, indépendamment de la structure globale des chaînes polymères. On les obtient par une variation continue de la composition d'alimentation principale dans laquelle on introduit, en parallèle ou en série, au moins une composition auxiliaire d'alimentation différente (et qui peut changer continuellement). Les copolymères obtenus peuvent présenter certaines caractéristiques spéciales de vitesse de réaction, de capacité de mouillage, etc. Le procédé s'applique notamment à la copolymérisation de l'oxyde d'éthylene et de l'oxyde de propylène.The invention describes copolymers derived from at least two cyclic organic monomers and which exhibit certain regulated characteristics. The copolymers are derived from organic monomers which can undergo ring-opening addition polymerization in the presence of an initiator containing active H. These copolymers have a predetermined ratio between the primary terminal OH and the secondary terminal OH, independently of the overall structure of the polymer chains. They are obtained by a continuous variation of the main feed composition into which is introduced, in parallel or in series, at least one different auxiliary feed composition (and which can change continuously). The copolymers obtained can exhibit certain special characteristics of reaction rate, wetting capacity, etc. The process applies in particular to the copolymerization of ethylene oxide and of propylene oxide.
