  • Publication number: 20110178262
    Abstract: The instant invention provides a method for improving the bubble stability of a polyethylene composition suitable for blown film extrusion process. The method for improving the bubble stability of a polyethylene composition suitable for blown film extrusion process comprises the steps of: (1) providing a polyethylene composition having a density in the range of 0.900 g/cm3 to 0.970 g/cm3 and an relaxation spectrum index (RSI) value in the range of 10 to 100; (2) oxygen tailoring said polyethylene composition; (3) thereby forming an oxygen tailored polyethylene composition, wherein the RSI value of the said oxygen tailored polyethylene composition increases from 10% to 300% of its initial value; (4) thereby improving the bubble stability of said polyethylene composition.

  • Publication number: 20110137086
    Abstract: In an improved process for telomerizing butadiene, contact butadiene and an organic hydroxy compound represented by formula ROH (I), wherein R is a substituted or unsubstituted C1-C20-hydrocarbyl and the organic hydroxy compound is not glycerol, in a reaction fluid in the presence of a palladium catalyst and a phosphine ligand represented by formula PAr3 (II), wherein each Ar is independently a substituted or unsubstituted aryl having a hydrogen atom on at least one ortho position, at least two Ar groups are ortho-hydrocarbyloxyl substituted aryls. The phosphine ligand has a total of two (2), three (3), four (4), five (5), or six (6) substituted or unsubstituted C1-C20-hydrocarbyloxyls, and optionally, any two adjacent substituents on an Ar group can be bonded to form a 5- to 7-membered ring.

  • Publication number: 20110136930
    Abstract: Viscoelastic polyurethane foam is prepared by using certain additives in the foam formulation. The additives include 1) alkali metal or transition metal salts of carboxylic acids; 2) 1,3,5-tris alkyl- or 1,3,5-tris (N,N-dialkyl amino alkyl)-hexahydro-s-triazine compounds; and 3) C1-12 carboxylate salts of quaternary ammonium compounds. The additives significantly improve processing and in particular permit the use of higher isocyanate indices, which helps to improve foam physical properties.
