Patent number: 11130869Abstract: Copolymer dispersions containing polyamide segments in aqueous media form binders for coatings for various industrial and construction materials. The copolymers have a high percentage of amide linkages. The copolymers are linked into higher molecular weight species by reactions with polyisocyanates (which forms urea linkages if the other reactant is an amine or a urethane linkage if the other reactant is a hydroxyl group).Type: GrantFiled: August 7, 2015Date of Patent: September 28, 2021Assignee: Lubrizol Advanced Materials, IncInventors: Gabor Erdodi, Naser Pourahmady, Yutao Yang, Jonathan J.

Patent number: 10442951Abstract: The present invention provides an economical route to environmentally friendly polymeric coatings with a high content of raw materials from renewable resources. These polymeric coatings offer performance characteristics that are competitive with conventional coating systems. The unique polymers on which this invention is based are copolymers of triglyceride oils, such as soybean oil, linseed oil, or another natural oil, with a vinyl compound, such as an acrylate or methacrylate, or a vinyl aromatic monomer. The present invention more specifically discloses a water dispersible, self-crosslinkable prepolymer composition which is comprised of a triglyceride oil having appended thereto (1) hydroxyl groups, (2) epoxy groups, (3) moieties which contain at least one aldehyde group or at least one ketone group, and (4) moieties which contain at least one vinyl and/or substituted vinyl group. In one embodiment of this invention the moiety which contains at least one vinyl group is derived from maleic anhydride.Type: GrantFiled: November 28, 2016Date of Patent: October 15, 2019Assignee: Lubrizol Advanced Materials, Inc.Inventor: Anthony D.

Patent number: 10266651Abstract: Water dispersible polyamides having carboxylic acid groups are disclosed. These are made by reacting polycarboxyl is acids or anhydrides thereof with amine containing monomer or an amide terminated polyamide under reaction conditions such that a few of the carboxylic acid groups are residual and can promote dispersion in water. These polyamides after dispersion can be chain extended to higher molecular weight polymers or can be terminally functionalized with reactive groups such as isocyanate, epoxy, vinyl, acetoacetonate, or silanol groups. Composites and hybrids of these polyamides with vinyl polymers are also disclosed and claimed.Type: GrantFiled: December 14, 2015Date of Patent: April 23, 2019Assignee: Lubrizol Advanced Materials, Inc.Inventors: Anthony D. Pajerski, Gabor Erdodi, Naser Pourahmady

Patent number: 9988555Abstract: Polymers are disclosed that incorporate large portions of elastomeric polyamide oligomers connected with polyisocyanates. These polymers have enhanced properties over similar polyurethanes due to better hydrolysis resistance of polyamides over polyesters and better UV resistance of polyamides over polyethers. Polyurea linkages can also improve properties over polyurethane linkages. Composites and hybrids of these polymers and other polyamides with vinyl polymers are also disclosed and claimed.Type: GrantFiled: February 3, 2014Date of Patent: June 5, 2018Assignee: Lubrizol Advanced Materials, Inc.Inventors: Gabor Erdodi, Naser Pourahmady, John Ta-Yuan Lai, Anthony D.

Patent number: 8568889Abstract: Aqueous polyurethane dispersions are made from urethane prepolymers comprising one or more polyhydroxy compounds from ketone functional molecules derived from an epoxidized natural oil. Addition of a hydrazine functional moiety to the prepolymer dispersion can further provide a crosslinking mechanism resulting in the formation of azomethine linkages in the resulting polyurethane during drying. When the ketone functional molecule is derived from levulinic acid and epoxidized vegetable oil, the resulting urethane dispersion can also be converted into a hybrid polyurethane-vinyl dispersion by adding and polymerizing one or more vinyl monomers in the polyurethane prepolymer or polyurethane dispersion.Type: GrantFiled: February 16, 2009Date of Patent: October 29, 2013Assignee: Lubrizol Advanced Materials, Inc.Inventors: Anthony D.
