  • Patent number: 6617397
    Abstract: The surface energy of polymeric substrates is increased by the application or incorporation of novel amphiphilic block copolymers. The block copolymer additives comprise a linear hydrophilic polymer or oligomer and a random hyperbranched polymer or oligomer and is completely or partially terminated with lipophilic end groups. The polymeric articles or constructions which benefit from the application or incorporation of the amphiphilic block copolymers in the areas of anti-fog, dissipation of static electricity, paintability, dyeability, printability, wicking of moisture, adhesion and polymer compatibility include carpet fibers, composite fibers, agricultural films, nonwoven coverstock, exterior automotive bumper fascia, packaging, hygienic products, incompatible polymer blends, laminated articles and eyewear.

  • Publication number: 20030135004
    Abstract: A composition, comprising, in an appropriate medium, at least one polymer with a highly specific ordered structure is disclosed. These compositions find a specific application in the field of make-up and are capable of being applied to keratinous fibres, in particular to the nails, eyelashes, eyebrows and hair. In particular, these compositions can make it possible to obtain a film which exhibits good resistance to chipping, to impacts, to rubbing movements, to scratches and/or to pressing actions.

  • Patent number: 6586533
    Abstract: Articles are formed from a thermosetting composition based on polybutadiene or polyisoprene resins which are subjected to a high temperature cure step of greater than 250° C. The thermosetting compositions may include fillers such as particulate ceramic fillers and may also include woven webs for improved dimensional stability and decreased brittleness. The formation process of this invention is particularly well suited for making electrical circuit substrates for microwave and digital circuits, typically in the form of the thermosetting composition being laminated on one or both opposed surfaces to metal conductive foil (e.g., copper).

  • Patent number: 6582791
    Abstract: A vinyl graphic marking film or label coated with a pressure sensitive acrylic adhesive designed to achieve high or permanent adhesion to polymeric low energy surfaces is disclosed. In addition to good adhesion to low energy surfaces, the graphic marking film or label may have microperforated or micro-rough edges which initiate tearing when removal is attempted. The article maintains flexibility and film strength for easy fabrication in graphic marking film or label manufacture.

  • Patent number: 6541543
    Abstract: An activated, substantially water soluble poly(ethylene glycol) is provided having of a linear or branched poly(ethylene glycol) backbone and at least one terminus linked to the backbone through a hydrolytically stable linkage, wherein the terminus is branched and has proximal reactive groups. The free reactive groups are capable of reacting with active moieties in a biologically active agent such as a protein or peptide thus forming conjugates between the activated poly(ethylene glycol) and the biologically active agent.
