  • Publication number: 20140001395
    Abstract: A binder composition, obtained by polymerizing acrylic acid monomer in water in the presence of a cure accelerator comprising an alkali metal salt of a phosphorous-containing inorganic acid to form a low molecular weight polyacrylic acid and subsequently reacting said low molecular weight polyacrylic acid with a polyhydroxy crosslinking agent in a crosslinking step to make a composition suitable for use as a component in a binder for fiberglass. A significant improvement involves conducting the crosslinking step in the absence of added catalyst. Moreover, satisfactory results are obtained in the absence of conventional undesirable sulfur odors.

    Abstract: Articles that contain a solid support with a grafted chain extending from the solid support, methods of making these articles, and various uses of the articles are described. More specifically, the grafted chain has a functional group that can react with or interact with target compound. Alternatively, the functional group on the grafted chain can react with a modifying agent to provide another group that can react with or interact with the target compound. The grafted chains are attached to the solid support through a ring-opened azlactone group. The articles can be used to purify the target compound or to separate the target compound from other molecules in a sample.
