    摘要: Higher molecular weight linear α-olefins are produced by the oligomerization of ethylene using certain iron complexes of 2,6-diacylpyridinedimimines or 2,6-pyridinedicarboxaldehydedimines as catalysts. These iron complexes are more sterically hindered than those heretofore used. The resulting α-olefins are useful as comonomers in olefin polymerizations.

    摘要: An ethylene oligomerization catalyst that oligmerizes ethylene to a series of α-olefins and that has a Schulz-Flory constant of about 0.75 to 0.995 produces a stream of α-olefins. This stream is then added to a vessel containing ethylene and a copolymerization catalyst that copolymerizes ethylene and α-olefins. The resulting branched polyethylene often has good processing properties. The good processing is presumably due to the presence of “long chain branching”. Such polymers are useful for films and other packaging materials, and for molding resins for molding parts such as industrial, automotive or electrical parts.

    摘要: Disclosed herein are processes for making quaternary chalcogenide wafers. The process comprises heating a mixture of quaternary chalcogenide crystals and flux and then cooling the mixture to form a solidified mixture comprising ingots of quaternary chalcogenide and flux. The process also comprises isolating one or more ingots of quaternary chalcogenide from the solidified mixture and mounting at least one ingot in a polymer binder to form a quaternary chalcogenide-polymer composite. The process also comprises optionally slicing the quaternary chalcogenide-polymer composite to form one or more quaternary chalcogenide-polymer composite wafers. The quaternary chalcogenide wafers are useful for forming solar cells.
