  • Patent number: 6211317
    Abstract: Copolymers based on unsaturated dicarboxylic acid derivatives, oxyalkylene glycol alkenyl ethers, unsaturated dicarboximides and/or -amides and vinyl monomers are described, as also their use as additives for hydraulic binders, especially cement. The copolymers also have an excellent plasticizing effect—even if they are added in large quantities—when used in concrete mixtures with an extremely low water content, and they do not retard the setting process.

  • Patent number: 6156861
    Abstract: Carbamate-functional allyl monomers and methods for making them are disclosed. The monomers, which are easy to prepare, readily polymerize with common ethylenic monomers to give low-molecular-weight resins without the need for solvents or chain-transfer agents. Coatings made from the resins should have good durability, good acid etch resistance, good mar resistance, high gloss, and high DOI.

  • Patent number: 6143849
    Abstract: Multifunctional chelating groups are covalently bound to acrylate or methylate monomers. These monomers are polymerized. The resulting polymers are highly substituted with chelating groups and are useful for removing metals from fluids such as liquid hydrocarbons. An example of a polymer according to this invention has the following structure: ##STR1## wherein Q is a saturated or unsaturated aliphatic group having 1 to about 200 carbon atoms and is typically an unsubstituted unbranched alkylene, a substituted unbranched alkylene, a substituted branched alkylene, or an unsubstituted branched alkylene, and is an integer having a value of at least 1.

  • Patent number: 6123928
    Abstract: Novel polymeric biologically inert compositions and their intermediates, as well as sunscreen formulations comprising them and making them invisible, are provided for broad range protection from ultraviolet radiation. Acryl polymers comprising at least two different ultraviolet absorbing moieties having different light absorbing ranges are employed in conjunction with other monomers to provide sunscreen polymers as microparticles. The polymer microparticles, once imbibed with carrier compounds, change the refractive index, thus providing invisible sunscreen formulations which offer enhanced protection without adverse physiological effects.
