Abstract: A process has been developed for decolorizing (and/or hydrogenating, and/or dehalogenating) a halogen containing unsaturated feedstock and/or polymeric resins. The process has the advantage of being substantially less affected by prolonged exposure to halogen contaminants and impurities than typical hydrogenation catalysts. A novel catalyst comprising (a) one or more metals selected from the group consisting of the metals in Group 8, Group 9 Group 10 and mixtures thereof; (b) one or more promoters selected from the group consisting of oxides of the elements in Group 1, Group 2, the Lanthanides group, the Actinides group and mixtures thereof; and (c) a support has also been developed.

Abstract: Tackifiers having Mn's of 5,000 or less and Tg's above 0.degree. C. are produced by combining a single site catalyst with an alpha-olefin and a cyclic monomer under conditions designed to produce low molecular weight.

Abstract: Disclosed are hot melt adhesives comprising tackifier and a high M.sub.w, narrow MWD, narrow CD ethylene/alpha-olefin copolymer(s) and a low M.sub.w, narrow MWD, narrow MWD ethylene/alpha-olefin copolymer prepared with either supported or unsupported cyclopentadienyl derivatives of Group IV and catalysts for applications in hot melt adhesives, particularly in automotive product assembly, packaging and food packaging. These ethylene copolymers have a M.sub.w ranging from about 20,000 to about 100,000, an MWD of less than 6 and 3 to 17 mole percent comonomer, and composition distribution breadth index above 70 percent. These ethylene copolymer blends have a M.sub.w ranging from about 20,000 to about 100,000 and an MWD of less than 6. In addition, the copolymer blends have comonomer mole percent ranging from about 3 to about 17.

Abstract: This invention relates to a method to process narrow molecular weight distribution polyolefins, particularly thermoplastics, polyethylenes, polypropylenes, and polyacrylates, whether they are homopolymers or copolymers. The process may be used in any extruder and is typically implemented along the extruder screw and/or barrel by heating the first zone the screw/barrel to place the polyolefin into a molten, flowable state. Thereafter, the polymer is cooled in the second heating zone to a point 50.degree. C. above or 10.degree. C. below the crystalline melting temperature of the polymer and thereafter is reheated in the final heating zone to a molten, flowable state and finally extruding it within 5 seconds or less through the die.

Abstract: A method to produce a stretch cling film possessing cling without added tackifier or acrylate unit is disclosed. Preferred copolymers to make this film have a solubility distribution breadth index of less than about 35.degree. C. and are ethylene/C.sub.3-20 alpha olefin copolymers with greater than about 4 to about 20 mole percent comonomer content.

Abstract: Disclosed are hot melt adhesives comprising ethylene/alpha-olefin copolymers prepared with either supported or unsupported metallocene-alumoxane catalysts for applications in hot melt adhesives used in automotive product assembly, packaging and food packaging. These ethylene copolymers have weight average molecular weight ranging from about 20,000 to about 100,000 and comonomer weight percent ranging from about 6 to about 30. The hot melt adhesive composition includes the ethylene copolymer and a compatible tackifier at a ratio of tackifier to copolymer of from 70:30 to 30:70 and may also include up to 30 weight percent of a paraffinic and microcrystalline wax of the copolymer and tackifier.

Abstract: The present invention provides for polymeric stabilizers which are the acid-catalyzed reaction product of a phenolic compound or a ring substituted aromatic compound and an olefin polymer containing either terminal unsaturation and/or pendant unsaturation along the polymer chain. These stabilizers are readily compatiable with olefin polymer and copolymer matrixes and offer good protection of the matrix polymer against one or more of heat, oxygen, ultra violet or radiation degradation. Other advantages include low volatilization as well as low tendency to migrate from the polymer matrix.
