Patent number: 11891485Abstract: A method of forming a three-dimensional object comprised of a silicone polymer is carried out by: (a) providing a silicone dual cure resin; (b) forming a three-dimensional intermediate from that resin, where the intermediate has the shape of, or a shape to be imparted to, the three-dimensional object, and where the resin is solidified in that intermediate object by irradiating with light; and then (c) further reacting the three-dimensional intermediate to form the three-dimensional object. The silicone dual cure resin includes: (i) a light polymerizable first reactant; (ii) a photoinitiator; (iii) at least one additional reactant(s), and (iv) optionally a catalyst. At least one of the first reactant and the additional reactant(s) contains a siloxane linkage.Type: GrantFiled: November 4, 2016Date of Patent: February 6, 2024Assignee: Carbon, Inc.Inventors: Jessica D. Drazba, Jason P. Rolland

Patent number: 11142635Abstract: Silane-crosslinkable polymeric compositions comprising a polyolefin having hydrolyzable silane groups, an acidic silanol condensation catalyst, and a phenolic antioxidant. The phenolic antioxidant has a phenol-based moiety fused with a cyclic ether where the oxygen atom of the cyclic ether is located in the para position relative to the hydroxyl group of the phenol-based moiety. Such crosslinkable polymeric compositions can be employed in various articles of manufacture, such as in the wire and cable industry.Type: GrantFiled: November 1, 2016Date of Patent: October 12, 2021Assignee: Dow Global Technologies LLCInventors: Dachao Li, Jessica D. Drazba, Manish Talreja, Jeffrey M. Cogen, Timothy J. Person, Paul J. Caronia
