    Abstract: The present invention relates to a superabsorbent polymer that not only has excellent basic absorption performance, but also exhibits more improved absorption speed, permeability, etc., and a method for preparing the same. The superabsorbent polymer includes a base polymer powder including: a first crosslinked polymer of water soluble ethylenically unsaturated monomers having acid groups of which at least a part are neutralized; and a surface crosslink layer that is formed on the base polymer powder, and further includes a second crosslinked polymer in which the first crosslinked polymer is additionally crosslinked by a C2-5 alkylene carbonate, wherein an absorption degree, SFC, an absorption speed, and a porosity fulfill specific ranges.

    Abstract: A composition of matter including a mother solution; an organic ester; an additive agent and deionized water. The mother solution includes a rare earth compound or a metal compound, an organic acid, an organic amine, and deionized water. Also provided is a method of preparing the composition of matter. The method includes: 1) heating deionized water to a temperature of 50-60° C.; adding an organic acid to the deionized water, allowing to dissolve, followed by addition of a rare earth compound or a metal compound, 2-4 hours later, adding an organic amine, heating to a temperature of 70-80° C. and holding; cooling and filtering to yield a mother solution; 2) mixing the mother solution, deionized water, and a catalyst; vacuumizing a resulting mixture, heating the mixture to a temperature of 95-125° C. and holding, following by addition of a polymerization inhibitor and an organic ester; 2-4 hours later, cooling, standing, separating.

    Abstract: A bitumen cutback composition is described substantially comprising Compound A with a formula: R1-X—R2  [COMPOUND A] where R1 is alkyl or phenyl hydrocarbon group; X is an O—C═O group; and R2 is a C1-C13 hydrocarbon chain branched or non-branched, with none, one, or more than one, oxygen interruption(s).
    The bitumen cutback composition may comprise: alkyl esters of fatty acids, esters of trihydroxy alcohols, mono ester, or di, or tri, hydroxy alcohols, phenyl alkyl esters, phenoxy alcohols and their esters, ether alcohols and their esters, and combinations thereof. Cutback bitumen mixtures are described comprising bitumen; and bitumen cutback composition. The cutback bitumen mixtures may be configured as a hot mix composition; a cold mix composition; or an emulsion, the emulsion further comprising an aqueous compound. Methods of temporarily reducing a viscosity of bitumen and methods of applying bitumen to a substrate are also described.
