Abstract: Methods of preparing a three-dimensional structure are provided. One method includes the steps of extruding beads of thixotropic thermoset materials, and subjecting the beads to curing conditions such that the thixotropic thermoset materials at least partially cure to form cured polymer layers. In some cases, the curing conditions are not applied until multiple beads are extruded and in contact with one another. The steps of these methods can be performed repeatedly as desired to prepare a three-dimensional structure of nearly limitless shapes by additive manufacturing processes. Thixotropic thermoset materials are also provided, as are three-dimensional objects formed therefrom.

Abstract: Plastic compositions that include one or more plasticizers containing acylated phenolated fatty acid esters and methods for making same are provided. In some examples, the plastic composition can include a polymer and a plasticizer. The polymer can be or include a polyvinyl chloride, a polyvinylidene chloride, a cellulose ester, a cellulose ether, a cellulose nitrate, a polyacrylate, a polyurethane, a copolymer thereof, or any mixture thereof. The plasticizer can be or include an acylated phenolated fatty acid monoester, an acylated phenolated fatty acid diester, or a mixture thereof. The plastic composition can include the plasticizer in an amount of about 10 wt % to about 60 wt %, based on a combined weight of the polymer, any acylated phenolated fatty acid monoester, and any acylated phenolated fatty acid diester.

Abstract: Adhesives containing an aldehyde-based resin, a kraft lignin, and a surfactant and methods for making and using same are provided. In one or more embodiments, the adhesive can include an aldehyde-based resin; a kraft lignin; a surfactant; an alkaline compound; and water. The adhesive can have a viscosity of about 500 cP to about 5,000 cP, at a temperature of about 25° C. In one example, the adhesive can include about 20 wt % to about 40 wt % of the aldehyde-based resin, about 1 wt % to about 15 wt % of the kraft lignin, about 0.05 wt % to about 2 wt % of the surfactant, about 0.5 wt % to about 10 wt % of the alkaline compound, and about 45 wt % to about 70 wt % of water, where all weight percent values are based on a combined weight of the aldehyde-based resin, the kraft lignin, the surfactant, the alkaline compound, and the water.
