摘要： Blend compositions containing a novel homopolymer, the use of which allows the incorporation of more comonomer in the additional components of the blend (for the same overall density) resulting in increased tie molecule formation and improvement in properties such as ESCR, toughness and impact strength are disclosed. The homopolymers are important for applications where a high density is needed to ensure certain mechanical properties like abrasion resistance, indentation resistance, pressure resistance, topload resistance, modulus of elasticity, or morphology (for the chlorination of PE to CPE) and additional advantages such as melt processability. The blend can be obtained by dry or melt mixing the already produced components, or through in-situ production by in parallel and/or in series arranged reactors. These resins can be used in applications such as films, blow molded, injection molded, and rotomolded articles, fibers, and cable and wire coatings and jacketings and, various forms of pipe.

摘要： Disclosed is a novel ethylene copolymer by copolymerizing an ethylene and at least one comonomer selected from a compound represented by the formula H2C═CHR wherein R is an alkyl group or an aryl group, and a diene, by slurry polymerization process in the presence of a solid catalyst system comprising a support, a transition metal compound and an activator capable of converting the transition metal compound into a catalytically active transition metal complex. The produced copolymer has a density of from 0.870 to 0.980 and a molecular weight distribution (Mw/Mn) of from 3 to 10, and exhibiting GPC/FT-IR characteristics and CFC characteristics, both of which define a comonomer content distribution, wherein, in one aspect, the lower the molecular weight of a copolymer fraction in a molecular weight distribution of an ethylene copolymer, the lower the comonomer content of the copolymer fraction; and, in the other aspect, the higher the molecular weight of a copolymer fraction, the higher the comonomer content of the copolymer fraction, so that ethylene copolymer exhibits high impact strength and excellent ESCR properties. Further, the ethylene copolymer contains substantially no impurites such as a wax, a gel and the like. Thus, the ethylene copolymer and blend compositions therefrom can be advantageously used for the production of film, fibers, foams or sheets including blown film, cast films, laminate films, blow-molded articles, injection molded articles, pipes, coating materials for cables, and the like.

摘要： Metal complexes corresponding to the formula: ##STR1## wherein: L independently each occurrence is a delocalized, .pi.-bonded group that is bound to M, containing up to 50 nonhydrogen atoms; M is a metal of Group 3, 4 or the Lanthanide series of the Periodic Table of the Elements; Z is a covalently bound, divalent substituent of up to 50 non-hydrogen atoms having the formula, --(ER.sub.2).sub.m --, wherein E independently each occurrence is carbon, silicon or germanium, R independently each occurrence is selected from the group consisting of C.sub.1-20 hydrocarbyl, and C.sub.1-20 hydrocarbyloxy, with the proviso that in at least one occurrence R is C.sub.1-20 hydrocarbyloxy, and m is an integer from 1 to 3; X' is a neutral Lewis base ligand having up to 20 non-hydrogen atoms; X" independently each occurrence is a monovalent, anionic moiety selected from hydride, halo, hydrocarbyl, silyl, germyl, hydrocarbyloxy, amide, siloxy, halohydrocarbyl, halosilyl, silylhydrocarbyl, and aminohydrocarbyl having up to 20 non-hydrogen atoms, or two X" groups together form a divalent hydrocarbadiyl or neutral hydrocarbon group; n is a number from 0 to 3; and p is an integer from 0 to 2.
