Abstract:
The invention relates to an additive formulation for the anti-static finishing and improvement of the electrical conductivity of inanimate organic material made of (A) 1 to 50% by weight of an olefin-sulfur dioxide copolymer, (B) 1 to 50% by weight of a compound having alkaline nitrogen atoms with longer-chained hydrocarbon groups with at least 4 carbon atoms or an equivalent structural element, which ensures the solubility of (B) in the inanimate organic material, (C) 0.1 to 30% by weight of an acid soluble in oil, and (D) 1 to 80% by weight of an organic solvent with a high boiling point, wherein at least 80% by weight of the molecule types have a boiling point that is higher than 150ºC at normal pressure.
Abstract:
Embodiments of the disclosure include lubricious coatings. In an embodiment the disclosure includes a lubricious coating for a medical device including first and second coated layers. The first coated layer is between the second coated layer and the device surface and includes a vinyl pyrrolidone polymer and a photo reactive group. The second coated layer is in direct contact with the first coated layer and is a top coating that includes an acrylic acid polymer. The second coated layer can optionally include photoreactive groups. The coating was found to have a very low number of particulates (e.g., 10 mm or greater) which is very desirable for in vivo use.
Abstract:
The present invention relates to an agent in particular for the surface epilamization of an article comprising one or more molecules having the general formula (1): A-F wherein: - A is an anchor group comprising a moiety selected from the group consisting of silane groups, hydroxyl groups, catechol groups, phosphate groups, phosphonate groups, carboxylic acid groups, amine groups, thiol groups and any combination of two or more of the aforementioned groups and - F is a functionalizing group, wherein the functionalizing group comprises a branched polymer having a backbone and at least two side groups, wherein at least one of the side groups is a C1-20 hydrocarbon group or a perhalogenated C1-20 hydrocarbon group. The invention pertains to the technical field of epilame for timepiece mechanical parts.
Abstract:
The present invention relates to a copolymer comprising units derived from monomers (i) an α-olefin and (ii) an ethylenically unsaturated carboxylic acid or derivatives thereof esterified with a primary alcohol branched at the β- or higher position, wherein the copolymer has a reduced specific viscosity of up to 0.08. The invention further provides for a lubricating composition containing said copolymer. The invention further provides a method and use of controlling viscosity index by supplying to an oil of lubricating viscosity the copolymer with pendant groups. In addition, the copolymer of the present invention may be useful as a base oil replacement.
Abstract:
An anti-seize composition which is non-flowable and dimensionally stable at temperatures greater than about 120°F and dispensable at room temperature without the application of heat is provided. The composition includes a solid anti-seize lubricant, such as of metallic copper, metallic nickel, metallic aluminum, metallic lead, metallic zinc, graphite, calcium oxide, calcium carbonate, calcium fluoride, calcium stearate, lithium, molybdenum disulfide, boron nitride, barium sulfate, or combinations thereof. The anti-seize lubricant is dispersed in a carrier which is a solid at about room temperature. The carrier includes a grease with an ASTM D 217 penetration at 25°C from about 200 to about 400 mm, a matrix material, and a naphthenic petroleum oil having a viscosity of less than about 300 SUS at 100°F and having an API gravity at 60°F from about 23 to about 25. The matrix material is a polymeric material. Optionally, a refined petroleum wax may also be included.
