  • Patent number: 7144963
    Abstract: This invention relates to a process for controlling the architecture of copolymers of at least two unsaturated monomers, made by free-radical polymerization in the presence of a cobalt-containing chain transfer agent, including the control of molecular weight, degree of branching and vinyl end group termination, by varying at least one of the variables of molar ratio of monomers, their relative chain transfer constants, polymerization temperature and degree of conversion and amount of cobalt chain transfer agent; and polymers made thereby.

  • Patent number: 6258323
    Abstract: The apparatus and method of the present invention provides for conducting simultaneous multiple synthesis of general compounds, which often takes place under varied uneven conditions requiring heating, cooling, agitation, reagent/solvent additions to the reactor contents at each reaction vessel location, supply and maintenance of inert atmosphere and means to facilitate the reflux of the reactor contents. Thus, it becomes necessary to monitor and control the reaction conditions during the simultaneous multiple synthesis of general compounds. The apparatus allows the user to connect various independently controlling and conveying means to each reaction vessel through multiple ports provided on a stopper mounted on each reaction vessel. The apparatus of the present invention permits user to readily access the reaction vessels without interrupting the reactions occurring in the adjacent reaction vessels.

  • Patent number: 5714527
    Abstract: A water-borne road marking paint composition which includes a chelating agent capable of chelating iron ions to form a substantially colorless complex is provided. A road marking produced from the traffic paint of the present invention substantially reduces or prevents yellowing of white road marking from iron and iron compound debris strewn on the road surfaces. A method of reducing or preventing yellowing of a newly-applied road marking on a road surface of a water-borne road marking paint is also disclosed. The method comprises incorporating in the water-borne road marking paint a chelating agent capable of chelating iron ions to form a substantially colorless complex. Further reduction of yellowing of the road marking is observed when a pigment dispersant is incorporated in the water-borne road marking paint.
