Branch Content of Metallocene Polyethylene
Small-angle neutron scattering (SANS) is employed to investigate the structure and longchain branch (LCB) content of metallocene-catalyzed polyethylene (PE). A novel scaling approach is applied to SANS data to determine themole fraction branch content (φbr) of LCBs in PE. The approach also provides the average number of branch sites per chain (nbr) and the average number of branch sites per min...

متن کاملHeat Capacities of Polyethylene III . One Linear and One Branched Sample from 5 to 350
Heat capacities of two polyethyle ne samples. one linear with a de nsity of 0.973 g c m 3 and one branched with a density of 0.91 g c m 3, have been dete rmine d by adiabati c ca lorimetry from 5 to 360 K in a different experimen tal arra nge ment the n e mployed for studies of othe r polyeth ylene samples in thi s series. The heat capac ity behavior of these two samples confirms expectation s ...
متن کاملNanocrystal bilayer for tandem catalysis.
Supported catalysts are widely used in industry and can be optimized by tuning the composition and interface of the metal nanoparticles and oxide supports. Rational design of metal-metal oxide interfaces in nanostructured catalysts is critical to achieve better reaction activities and selectivities. We introduce here a new class of nanocrystal tandem catalysts that have multiple metal-metal oxi...
متن کاملHeterogeneous Catalysis for Tandem Reactions
As long as the molecular complexity increases, the number of chemical transformations will increase in parallel, becoming a highly demanding synthetic process in terms of time and resources. Since the loss of material after each purification step will also dramatically reduce the overall efficiency of a synthetic process, the conversion of such transformation into a practical and efficient proc...
