  • Publication number: 20100286434
    Abstract: New ethylenically unsaturated monomers are provided that can be (co)polymerized to provide a composition and method whereby the same group that is attached to or within the backbone of an associative thickener is reversibly switched between being hydrophilic and hydrophobic in nature. When the group that is attached to or within the backbone is rendered hydrophilic, the aqueous thickener is pourable and readily incorporated into aqueous polymer compositions. When this group is rendered hydrophobic, the thickener performs its thickening function efficiently. Switching is readily accomplished by adjusting the pH of the associative thickener composition and the aqueous polymer composition being thickened. The thickeners are prepared from the novel monomers by an aqueous solution polymerization.

    Abstract: A process for the conversion of aldehydes to esters, specifically acrolein or methacrolein to methyl acrylate or methyl methacrylate, respectively. Essentially in the absence of water, an aldehyde is contacted with an oxidizing agent to form an intermediate and then the intermediate is contacted with a diol or an alcohol to form an ester or diester. Preferably, the oxidizing agent is also a chlorinating agent. Specifically, acrolein or methacrolein is contacted with an oxidizing/chlorinating agent, such as t-butyl hypochlorite, and the chlorinated compound is contacted with an alcohol, such as methanol, to form methyl acrylate or methyl methacrylate, respectively. Generally, the order of addition is for the oxidizing agent to be added to the aldehyde, specifically for t-butyl hypochlorite to be added to acrolein or methacrolein, and for the diol or alcohol to be added to the intermediate, specifically for the methanol to be added to the reaction product of acrolein or methacrolein and t-butyl hypochlorite.

  • Publication number: 20030118736
    Abstract: The present invention provides a polymer that can be used as an anti-refelctive coating (ARC) polymer, an ARC composition comprising the same, methods for producing the same, and methods for using the same. The polymer of the present invention is particularly useful in a submicrolithographic process, for example, using KrF (248 nm) or ArF (193 nm) lasers as a light source. The polymer of the present invention comprises a chromophore that is capable of absorbing light at the wavelengths used in a submicrolithographic process. Thus, the ARC of the present invention significantly reduces or prevents back reflection of light and the problem of the CD alteration caused by the diffracted and/or reflected light. The ARC of the present invention also significantly reduces or eliminates the standing wave effect and reflective notching.
