    • This invention relates to a multiple phase polymerization process to produce polyolefins comprising contacting olefins and a homogeneous catalyst or catalyst system at a temperature between the melting point of the dry polymer and 80°C below the melting point of the dry polymer in the presence of a fluorinated hydrocarbon. This invention also relates to a process to produce polyethylene comprising contacting a homogeneous catalyst or catalyst system with ethylene and from 0 to 40 weight % of one or more C3 to C40 olefin comonomer(s) in the presence of a fluorinated hydrocarbon and optionally a hydrocarbon solvent at a temperature below the reaction medium melting point. This invention also relates to a process to produce polypropylene comprising contacting a homogeneous catalyst or catalyst system with propylene and from 0 to 50 weight % of one or more of ethylene and C4 to C40 olefin comonomer(s) in the presence of a fluorinated hydrocarbon and optionally a hydrocarbon solvent at a temperature below the reaction medium melting point.
    • 本发明涉及生产聚烯烃的多相聚合方法,其包括使烯烃和均相催化剂或催化剂体系在干聚合物的熔点和低于干聚合物熔点的80℃之间的温度下,在 氟化烃。 本发明还涉及一种生产聚乙烯的方法,其包括使均相催化剂或催化剂体系与乙烯和0至40重量%的一种或多种C 3至C 40烯烃共聚单体在氟化烃和任选的烃 溶剂在低于反应介质熔点的温度下进行。 本发明还涉及生产聚丙烯的方法,包括在氟化烃存在下使均相催化剂或催化剂体系与丙烯和0至50重量%的一种或多种乙烯和C 4至C 40烯烃共聚单体接触, 任选的烃溶剂在低于反应介质熔点的温度下。
