Abstract: Embodiments are directed to phosphaguanidine metal complexes of formula I and using those complexes in ?-olefin polymerization systems.

Abstract: A silsesquinoxane modified TiO2 sol, a method of forming the TiO2 sol, a radiation curable composition comprising the TiO2 sol and cured material formed from the radiation curable composition are disclosed. The TiO2 sol is at least partially covered by silsesquinoxane and has high RI useful for an insulating layer on indium tin oxide (ITO) electrodes that provides transparency of the ITO electrodes.

Abstract: A composition comprising a blend of high density polyethylene (HDPE) and a nucleating component, with optional additives, in amounts effective to provide reduced shrinkage of the extruded composition and components made from the composition.

Abstract: The present invention provides a self-collapsing, moisture curable one component polyurethane foam (1K PU) composition from moisture curable polyurethane prepolymers and to methods of making weather resistant barriers and formed in place gaskets therefrom. The foam compositions are packed under pressure with a blowing agent. In the methods, the foams are applied to gaps in the exterior (sheathing) of a building under construction and collapse on cure to enable application an aqueous weather barrier coating thereover within an hour. The foams also cure when applied on or adjacent a structure to form a foam gasket that enables installation of additional structural elements over or adjacent the foam gasket without bowing or damage to the structure treated.

Abstract: Apparatus for spectroscopic analysis which includes a tunable diode laser spectrometer having a digital output signal and a digital computer for receiving the digital output signal from the spectrometer, the digital computer programmed to process the digital output signal using a multivariate regression algorithm. In addition, a spectroscopic method of analysis using such apparatus. Finally, a method for controlling an ethylene cracker hydrogenator.
