The propylene polymerization processes generally include contacting propylene and an amount of ethylene with a first metallocene catalyst and a second metallocene catalyst within a polymerization reaction vessel to form a propylene based polymer, wherein the amount is an amount effective to form the propylene based polymer including from about 2 wt. % to about 6 wt. % ethylene, the second metallocene catalyst is capable of incorporating a greater amount of ethylene into the propylene based polymer than the first metallocene catalyst and wherein the first metallocene catalyst is capable of forming a propylene/ethylene random copolymer exhibiting a melting temperature that is greater than that of a propylene/ethylene random copolymer formed from the second metallocene catalyst.

摘要： A process for preparing low melting copolymers comprising contacting a mixture of olefin monomers with a CpFlu-type metallocene catalyst under reaction conditions sufficient to form a copolymer. The copolymers thus prepared desirably display melt temperatures from about 100° C. to about 140° C. and may be produced with reduced amounts of ethylene. The copolymers may also exhibit reduced levels of undesirable xylene solubles, relatively narrow molecular weight distribution, and other improved optical and physical properties.

摘要： Random copolymers may be prepared using a process that includes polymerizing a mixture of monomers including at least propylene and ethylene monomer, in the presence of a catalyst system including a metallocene catalyst having the general structure: racemic-X(2-R1-4-R2-Ind)2MCl2 wherein M is a Group 4, 5 or 6 transition metal, or a lanthanide or actinide series metal; X is a structural bridge imparting stereorigidity; R1 is hydrogen or an alkyl, aryl or a substitution moiety; R2 is hydrogen, or a C1-C4 alkyl; and Ind is an indenyl group. The copolymers are prepared under reaction conditions suitable to form a copolymer, wherein the copolymer has a higher level of ethylene incorporation than a corresponding polymer formed under otherwise identical reaction conditions except that a different bisindeny metallocene catalyst having a 4-indenyl substitution larger than 4 carbons is used. The copolymers may have a lower melt temperature than the corresponding polymers. The resulting copolymers may be used to prepare articles of manufacture including, but not limited to films, fibers and injection molded articles.
