    摘要: Exposing to visible light atom transfer radical polymerizations of vinyl monomers that use transition metal compounds often results in faster polymerizations and/or the need for less transition metal compound. Disclosed is a process for the polymerization of vinyl monomers by atom transfer radical polymerization using a first compound containing a transition metal and a second compound capable of radically transferring an atom or group to said first compound, wherein the improvement comprises, irradiating with visible light with an intensity of at least about 5 mW/cm.sup.2 a liquid in which said polymerization is taking place. The polymers made are useful for molding resins and coatings.

    摘要: Sensors (20, 50, 70) for use in detecting the presence of sugars and other analytes (target molecules). The sensor is composed of a metal complex that binds to the target molecule and releases a proton or includes an exchangable ligand which is exchanged for the target molecule during the binding interaction between the metal complex and the target molecule. The result of the binding interaction is the release of a proton, hydroxide ion or ligand species generated during the ligand exchange. Measurement of the release of proton, hydroxide ion or other ligand species from the sensor (20, 50, 70) provides an indirect indication of target molecule concentration. The metal complexes may be attached to support structures (10, 12) to provide both anchoring and positioning of the metal ions to increase selectivity of sugar/metal complex interactions. Detection systems in which pH is used as an indication of proton or hydroxide release are disclosed, as are detection systems in which Cl.sup.- release is used. Methods for monitoring the concentrations of sugars and related molecules using the metal based sensors (20, 50, 70) are also disclosed.

    摘要: A branched polyolefin, preferably a polyethylene, and containing branches with even and odd numbers of carbon atoms, may be made by oligomerizing ethylene to an &agr;-olefin using a selected iron containing catalyst, and then copolymerizing that &agr;-olefin with ethylene and one or more other added &agr;-olefins which have odd numbers of carbon atoms. The polymers are useful, for example, as molding resins.
