A liquid composition set contains a liquid composition X, containing a polymerizable compound X and a solvent X, and a liquid composition Y, containing a solvent Y. The liquid composition X is to form a porous resin. A liquid composition Z containing 10.0% by mass of the liquid composition X and 90.0% by mass of the liquid composition Y has a light transmittance of 30% or more at a wavelength of 550 nm, where the light transmittance is measured while the liquid composition Z is being stirred. A haze measuring element produced from the liquid composition Z has a haze increasing rate of 1.0% or more.

The present disclosure relates to a method for making a non-isocyanate polyurethane (NIPU) foam, where the method includes decomposing a blowing agent having at least one of an amine carbamate salt and/or an amine bicarbonate salt to form a diamine and CO.sub.2 in the presence of a molecule comprising a plurality of cyclic carbonate functional groups and reacting the diamine with at least a portion of the cyclic carbonate functional groups to form the NIPU foam. In some embodiments of the present disclosure, the reacting and the decomposing may occur at substantially the same rate.

A curative for epoxidized plant-based oils and epoxidized natural rubber is created from the reaction between a naturally occurring polyfunctional acid and an epoxidized plant-based oil is disclosed. The curative may be used to produce at least one of six different materials, wherein each type of material may be configured as a thermosetting elastomer that is crosslinked with ß-hydroxyester linkages. The materials may be configured as a leather-like material, a foam material, a molded elastomer, a coating, an adhesive, and/or a rigid or semi-rigid material. Illustrative articles made from any combination of the six materials may be recycled using a mechano-chemical process to de-crosslink the thermosetting elastomer.

Porous three-dimensional networks of polyurea and porous three-dimensional networks of carbon and methods of their manufacture are described. In an example, polyurea aerogels are prepared by mixing an triisocyanate with water and a triethylamine to form a sol-gel material and supercritically drying the sol-gel material to form the polyurea aerogel.

Subjecting the polyurea aerogel to a step of pyrolysis may result in a three dimensional network having a carbon skeleton, yielding a carbon aerogel. The density and morphology of polyurea aerogels can be controlled by varying the amount of isocyanate monomer in the initial reaction mixture. A lower density in the aerogel gives rise to a fibrous morphology, whereas a greater density in the aerogel results in a particulate morphology. Polyurea aerogels described herein may also exhibit a reduced flammability.

The present invention relates to a composition comprising an aqueous dispersion of first polymer particles functionalized with structural units of t-butyl methacrylate or t-butyl acrylate, and imbibed with a catalyst of Structure (I), where R, R.sup.1, R.sup.2 and R.sup.3 are as defined herein, and a process for making the composition. The present invention also relates to an aqueous dispersion of core-shell polymer particles, wherein the first polymer particles are encapsulated in a shell having a high T.sub.g. The imbibed first polymer particles and the core-shell polymer particles can be expanded in the dry state at significantly lower temperatures than reported in the prior art. ##STR00001##
