Process for producing a propylene/1-pentene polymer in the presence of a Ziegler-Natta catalyst system with the monomers reactants being in the vapor phase while the reaction is in process and with no liquid component being present in the reaction zone while the reaction is in progress. Different ways of introducing the reactants are disclosed (partly in liquid phase then immediately evaporated or not, preheated or not, mixed with the comonomer or not).
L'invention traite d'un procédé permettant de fabriquer un polymère de propylène/1-pentène en présence d'un système catalyseur Ziegler-Natta. Au cours de la réaction, les réactifs monomères sont en phase vapeur et la zone de réaction ne contient pas de composant liquide. L'invention concerne en outre diverses possibilités d'introduction de ces réactifs (partiellement en phase liquide, puis immédiatement évaporés ou non, préchauffés ou non, mélangés ou non avec le comonomère).
