  • Publication number: 20240110013
    Abstract: A method of preparation of olefin-functionalized fluorosilicones, the properties of which can be optimized, for example, as release liners for silicone adhesives, the method including subjecting a mixture of a hydride-functional polysiloxane, a first compound having a terminal monosubstituted olefin, and a second compound having both a terminal monosubstituted olefin and an internal disubstituted olefin to hydrosilylation conditions to provide a hydrosilylated fluorosilicone with internal olefins and reacting the hydrosilylated fluorosilicone with internal olefins with ethylene in the presence of an olefin metathesis catalyst to provide the olefin- functionalized fluorosilicone. Articles including such olefin-functionalized fluorosilicones.

  • Publication number: 20230054849
    Abstract: Silicone polyoxamide and silicone polyoxamide-hydrazide copolymers comprise at least two repeating units of formula (I). In this formula, each R1 is independently an alkyl, haloalkyl, aralkyl, alkenyl, aryl, or aryl substituted with an alkyl, alkoxy, or halo; each Y is independently an alkylene, aralkylene, or a combination thereof; each G is independently a bond or a divalent residue equal to a diamine of formula R3HN—G—HR3 minus the two —NHR3 groups; each R3 is independently hydrogen or alkyl or R3 taken together with G and with the nitrogen to which they are both attached form a heterocyclic group; each n is independently an integer of 0 to 300; each p is independently an integer of 1 to 25, and the average of p is 1.3 or greater; and each q is independently an integer of 1 to 2, and the average of q is no greater than 1.05.

  • Publication number: 20220259770
    Abstract: A core-sheath filament having a pressure-sensitive adhesive core and a non-tacky thermoplastic sheath that surrounds the core is provided. The pressure-sensitive adhesive core includes a) a silicone-containing block copolymer having multiple poly-diorganosiloxane segments plus b) a silicone tackifying resin. Additionally, methods of making the core-sheath filament and methods of using the core-sheath filament to print a pressure-sensitive adhesive are described.

  • Patent number: 10807046
    Abstract: Asymmetric articles are described including a porous substrate with two opposing major surfaces and a porous structure extending between the surfaces, and a polymeric coating on one of the major surfaces and extending into the porous structure to a depth of the porous structure. Methods for making an asymmetric composite article are also provided, including providing a porous substrate, treating the porous substrate with a plasma treatment or a corona treatment from one major surface to a depth of the porous structure between the two major surfaces. The method further includes applying a coating solution to the treated porous substrate and drying the coating solution to form a composite asymmetric composite article having a polymeric coating on one major surface and extending into the porous structure to the depth of the treated porous structure.

  • Publication number: 20150262262
    Abstract: A computerized system and method for the creation and management of fundraising events. The system and method support creation of fundraising groups comprising team members that participate in physical activity to raise donations for a certain entity or organization. Individual team members utilize a device (e.g., pedometer) that measures activity during a specified time period. Pledges for donations are made by sponsors that log into a website and pledge to donate a certain amount of money based on the physical activity performed by a fundraising team member. Some fundraising groups may comprise multiple teams. Different teams of the same group may have different fundraising goals or objectives. The website of the system may link a fundraising group to its different fundraising teams. All teams of a fundraising group may raise money for a single entity or the teams of a fundraising group may raise funds for different entities.
