  • Functional polymer with a pendant color changing indicator
    Patent number: 8329851
    Abstract: A functionalized polymer is disclosed that comprises the reaction product of a polymer having one or more pendant reactive functional groups and a color changing indictor having a co-reactive functional group. The co-reactive functional group of the color changing is able to react with the reactive functional group of the polymer to form a covalent bond. Therefore, the color changing indicator is pendant from the polymer. The color changing indicator maintains its ability to produce a visually discernable color change in the presence of an associated stimulus.

  • Electron beam apparatus having a low loss beam path
    Patent number: 6749903
    Abstract: An apparatus for irradiating an article, particularly a multi-layer article, with electron beam radiation is provided. The apparatus contains a window having a short unit path length and allows for controlled irradiation of an article such that upper portions of the article receive significantly higher electron beam dosages than lower portions of the article. Such differential dosage allows for modification of an article comprising a coating composition that can be modified by electron beam irradiation on a substrate that is vulnerable to degradation from electron beam radiation. A method of irradiating an article with electron beams, and products manufactured using the apparatus and method of the invention, are also disclosed.
