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).

Aqueous copolymer coating compositions for industrial and construction applications

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.

Water dispersible, self-crosslinkable prepolymer composition

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.

Water dispersible polyamide building blocks

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.

Water-borne polyamide-urea dispersions

An aqueous dispersion of polyurethane/acrylic polymer hybrid composites is made by forming a mixture of urethane prepolymer or polymer, acrylic monomer or polymer, ketone functional molecule/oligomers, and hydrazine functional molecule/oligomers; and dispersing the mixture so made in aqueous medium.

Aqueous dispersions of polyurethane/acrylic hybrid compositions

Thiocarbonate compounds are reacted with various polyols to introduce hydroxyl end groups thereto which can be subsequently reacted with urethane forming compounds to form various polyurethanes including block copolymers thereof.

Hydroxyl-terminated thiocarbonate containing compounds, polymers, and copolymers, and polyurethanes and urethane acrylics made therefrom

A product and processes comprising urethane polymer and at least one copolymer from a hydrophobic ethylenically unsaturated C-Colefins copolymerized with polar monomers such as acrylates. One process optionally utilizes an acid source to modify/catalyze the reactivity of the polar monomer and/or radically activated repeat unit from the polar monomer to promote incorporation of the ethylenically unsaturated olefin. Other processes vary depending on which polymer if formed and/or dispersed first. The hybrid copolymer shows excellent adhesion to a variety of polymeric and/or polar substrates such as polyolefins, acrylate coatings, wood, etc.

Dispersion of hybrid polyurethane with olefin-acrylic copolymerization

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.

Aqueous polymer compositions obtained from epoxidized natural oils

An aqueous dispersion of polyurethane composites is made by forming a dispersion of urethane prepolymer or polymer and ketone functional molecule by dispersing them in an aqueous media and adding a hydrazine functional molecule. When the ketone functional molecule is derived from levulinic acid and epoxidized vegetable oil, the resulting urethane dispersion has enhanced coalescence with less need for coalescing aids.

Aqueous dispersions of polyurethane compositions with ketone-hydrazide

An aqueous dispersion of polyurethane composites is made by forming a mixture of urethane prepolymer or polymer, ketone functional molecule/oligomers, and hydrazine functional molecule/oligomers; and dispersing the mixture so made in aqueous medium.
