The present application is directed to methods for preparation of polymer particles in gel form and carbon materials made therefrom. The carbon materials comprise enhanced electrochemical properties and find utility in any number of electrical devices, for example, as electrode material in ultracapacitors or batteries. The methods herein can also be employed generally to improve emulsion and/or suspension polymerization processes by improved control of diffusion of acidic and basic species between the polymer and secondary phases.

Binder compositions and methods for making and using same are provided. In at least one specific embodiment, the binder composition can include at least one unsaturated compound having two or more unsaturated carbon-carbon bonds and at least one free radical precursor. At least one of the unsaturated carbon-carbon bonds can be a pi-bond that is not conjugated with an aromatic moiety and can be capable of free radical addition. The free radical precursor can be present in an amount of about 7 wt % to about 99 wt %, based on the weight of the one or more unsaturated compounds.

Methods for making composite products are provided. In at least one specific embodiment, the method can include combining a plurality of lignocellulose substrates and one or more free radical precursors to produce a mixture of the lignocellulose substrates and the one or more free radical precursors. The method can also include maintaining the mixture at a temperature less than 60 C. for at least 10 minutes while retaining at least 11 wt % of the one or more free radical precursors charged to the mixture. The method can then include heating the mixture comprising at least 11 wt % of the one or more free radical precursors charged to the mixture to a temperature of at least 60 C. to about 300 C. to produce a composite product. The composite product can have a density less than 1 g/cm^(3 )and an internal bond strength of at least 0.35 MPa.


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.

A method for making a composite product can include combining a plurality of lignocellulose substrates and a binder to produce a resinated furnish. The binder can be or include a polyphenolic compound, a free radical precursor, and an unsaturated compound having two or more unsaturated carbon-carbon bonds. At least one of the unsaturated carbon-carbon bonds is a pi-bond that is not conjugated with an aromatic moiety and is capable of free radical addition. The method can also include pressing the resinated furnish between at least two surfaces in a press, where at least one of the at least two surfaces can be a porous surface, and at least partially curing the binder in the resinated furnish to produce a composite product.


Treated aldehyde-based resins containing one or more polyamines and methods for making and same. The treated aldehyde-based resin can be or include an aldehyde-based resin and a polyamine. The polyamine can be or include one or more aromatic polyamines, one or more poly(C_(2)-C_(5 )alkylene) polyamines, or a mixture thereof. The treated aldehyde-based resin can include about 0.05 wt % to about 10 wt % of the polyamine, based on a solids weight of the aldehyde-based resin.

Resin systems and methods for making and using same are provided. The method for making a paper product can include contacting a plurality of pulp fibers with a resin system. The resin system can include a first polyamidoamine-epihalohydrin resin and a second resin that can include a second polyamidoamine-epihalohydrin resin, a urea-formaldehyde resin, or a mixture thereof to produce a paper product. The first resin and the second resin can be sequentially or simultaneously contacted with the plurality of pulp fibers. The period for sequential addition between the first resin and the second resin is about 1 second to about 1 hour.
