  • Patent number: 6770701
    Abstract: The present invention is directed to a method for producing a copolymer and a copolymer product of the method. The copolymer is prepared by a controlled radical polymerization process, typically an atom transfer radical polymerization process, in which polymerizable alkene monomers are polymerized in the presence of a halogenated polyolefin macroinitiator. The copolymer product of this process is useful in a film-forming composition that adheres strongly to polyolefinic substrates and to which non-polyolefinic film-forming compositions strongly adhere. The copolymer can be applied to a substrate in an adhesion-promoting layer or can be incorporated into a film-forming composition, such as a primer, that contains additional resinous compounds.

  • Patent number: 6750285
    Abstract: One embodiment is directed to an adhesive composition that is clear, flexible, and is devoid of non-polar additives and comprises molecules that are polar and particles having a lipophilic surface. In one embodiment, the particles range from 7 nm to 3 &mgr;m in diameter and the adhesive layer is between 0.1 and 5 &mgr;m thick. The particles may be alkyl-converted fumed silica, porous polymer-coated surfaces, or styrene/divinyl benzene polymer. The particles absorb non-polar oils or lubricants that prevent adhesion between printable media and the adhesive layer of the film. The present disclosure is a general solution for oily or lubricated substrates or printed areas. Oily materials are used in inks, dry powder toners, liquid EP toners, and in printers and copiers. The present teachings allow the adhesive to bond well to print media surfaces.

  • Patent number: 6620874
    Abstract: A method of making ionomeric particulate compositions by suspension polymerization are provided. The method comprises the steps of (a) forming an aqueous phase comprising an acid monomer, a metal oxide, and at least a first and a second surfactant, the first being a monomer surfactant; (b) forming an oil phase comprising at least one vinyl monomer; and (c) suspension polymerizing the aqueous phase with the oil phase to yield an ionomeric particulate composition. The resulting particulates do not have pressure sensitive tack. Particle size in the range of less than 10 micrometers can be made. The ionomeric particulate is made in the absence of a chain transfer agent and thus can have high molecular weight.
