A polymerization process comprises contacting one or more olefinic comonomers in the presence of at least a high molecular weight catalyst and at least a low molecular weight catalyst in a single reactor; and effectuating the polymerization of the olefinic comonomers in the reactor to obtain an olefin polymer. Preferably, both catalysts have the ability to incorporate a substantially similar amount of comonomers in the olefin polymer. The polymers produced by the process may have a relatively higher level of long chain branching while maintaining a relatively narrow molecular weight distribution, i.e., MWD less than about 6. These interpolymers may exhibit processability similar to or better than LDPE but have physical properties similar to metallocene catalyzed polymers.
一种聚合过程包括在单个反应器中,在至少高分子量催化剂和至少低分子量催化剂的存在下,接触一种或多种烯烃共聚物,并在反应器中使烯烃共聚物聚合以获得烯烃聚合物。最好是,两种催化剂都能够在烯烃聚合物中包含大致相似数量的共聚物。该过程生产的聚合物可能具有相对较高的长链支化
水平,同时保持相对较窄的分子量分布,即MWD小于约6。这些互穿聚合物可能表现出类似于或优于LDPE的加工性能,但具有类似于
金属卡宾催化的聚合物的物理性质。
