Patent number: 11661365Abstract: A composition and method of inhibiting corrosion and white rust on metal components in a water system. The composition preferably comprises an amino-acid based polymer (most preferably a polyaspartic acid or a salt thereof), hydroxyphosphonoacetic acid, and a second phosphonic acid (preferably a phosphonocarboxylic acid), and does not require the use of regulated metals. The composition is effective even in the presence of biocides. A preferred method of inhibiting white rust comprises adding an amino-acid based polymer or hydroxyphosphonoacetic acid or both to the water system. A preferred method of inhibiting corrosion or white rust comprises adding an amino-acid based polymer, hydroxyphosphonoacetic acid, and a phosphonocarboxylic acid to the water system. Preferably the active concentrations are at least 3 ppm each of the amino-acid based polymer and hydroxyphosphonoacetic acid when added to a volume of water in the water system.Type: GrantFiled: May 30, 2019Date of Patent: May 30, 2023Assignee: NCH CorporationInventors: Marta Drewniak, Lyle H.

Patent number: 11104587Abstract: A system and method of controlling the treatment of water systems comprises multiple feeders for separately feeding treatment products, in the form of concentrated, non-hazardous, liquids with a single active ingredient, to a water system to treat various issues, such as corrosion and biofilms. A sensor verifies delivery of the treatment product to the water system. A controller controls activation of each feeder to control a feed rate according to programmed functions. The controller receives signals from sensors, which can be used as inputs in calculating feed rates or feeder activation times according to the programed functions and can alter treatment product feed rates based on real time data regarding water system chemistry or flow rates. The controller can send and receive data, signals, alerts, alarms or changes in programming to or from remote users, remote computers, or a water system controller.Type: GrantFiled: February 28, 2018Date of Patent: August 31, 2021Assignee: NCH CorporationInventors: Marta Drewniak, Lyle H. Steimel, James Victor List, Cory J. Holder, Scott M. Boyette

Patent number: 7740951Abstract: Multilayered structures formed from two or more polymeric layers are fabricated to obtain a single structure preferably having advantages of each of the separate layers. Polyolefin-based substrates can provide a layer with a good balance of stiffness and impact resistance, excellent processability, and relatively lower cost. Tie layers, preferably physically positioned adjacent a polyolefin-based substrate layer, facilitates adhering additional layer(s) together with the polyolefin-based substrate. Suitable tie layers generally include a multicomponent blend of at least one vinyl cyanide-containing component and at least one styrenic block copolymer component. Preferably, the additional layers include at least one acrylate-based cap layer, which can have a glossy, scratch resistance outer layer with excellent optical characteristics.Type: GrantFiled: April 11, 2007Date of Patent: June 22, 2010Assignee: LyondellBasell Advanced Polyolefins USA Inc.Inventors: Tara Thomasson, Kyle Davis, Marta Drewniak

Patent number: 6770697Abstract: The invention includes a process for preparing an improved melt-strength polyolefin blend by incorporating a polyolefin/clay nanocomposite product. The nanocomposite-modified polyolefin blend is used to form articles through processing operations that involve stretching and/or drawing, such as thermoforming, melt spinning, blow molding and foaming. The addition of the nanocomposite product to the polyolefin blend improves the sag resistance of the polyolefin and broadens the processing window of the operation.Type: GrantFiled: February 7, 2002Date of Patent: August 3, 2004Assignee: Solvay Engineered PolymersInventors: Marta Drewniak, Xia Zhao, Satchit Srinivasan
