摘要:
Syndio-isoblock polymers of 1-olefins having molecular chains which contain syndiotactic and isotactic sequences are obtained if the polymerization of the 1-olefins is carried out using a catalyst which is composed of a bridged chiral metallocene of the formula I and an aluminoxane. The polymers have some rubber-like properties.

摘要:
Isoblock polymers of 1-olefins with a narrow molecular weight distribution are obtained when 1-olefins are polymerized using a catalyst consisting of a chiral metallocene, containing bridges, of formula I: and an aluminoxane. The polymers have rubber-like properties.

A stacking adapter is disclosed. The stacking adapter includes a lower surface, an outer upper surface arranged opposite an inner upper surface, an outer peripheral sidewall surface that connects the outer upper surface to the lower surface, and an inner peripheral sidewall surface that connects the inner upper surface to the lower surface. An assembly is also disclosed.
摘要:
Methods and apparatus that facilitate predictive hard and soft handover are presented herein. A measurement component can measure signal strength data associated with a source cell and one or more target cells. One or more linear regression lines can be computed based on the signal strength data. Rates of at least one of an increase or a decrease in the signal strength data per unit of time can be determined based on a slope of the one or more linear regression lines—the slope can comprise a change in signal strength data per unit of time. A time to trigger at least one of a hard or soft handover can be triggered based on the rates.
