    Abstract: Styrenic (meth)acrylic oligomers that are prepared at lower temperature than conventional solid grade oligomers, or are hydrogenated, contain fewer terminal vinylic unsaturations, when compared to such conventional styrenic (meth)acrylic oligomers prepared by the customary high temperature processes. Styrenic (meth)acrylic oligomers that contain fewer terminal vinylic unsaturations demonstrate improved thermal stability and may provide improved resistance to UV weathering compared to the conventional and non-hydrogenated styrenic (meth)acrylic oligomers.

    Abstract: .A proppant includes a particle present in an amount of from 90 to 99.5 percent by weight and a polymeric coating disposed about the particle and present in an amount of from 0.5 to 10 percent by weight, based on the total weight of the proppant.The polymeric coating includes the reaction product of an acrylate copolymer and an isocyanate. The acrylate copolymer includes styrene units and has a hydroxyl number of from 20 to 500 mg KOH/g. A method of forming the proppant includes the steps of combining the acrylate copolymer and the isocyanate to react and form the polymeric coating and coating the particle with the polymeric coating to form the proppant.

    Abstract: Un agente de soporte comprende una partícula presente en una cantidad de 90 a 99.5 por ciento en peso basado en el peso total del agente de soporte, y un revestimiento polimérico dispuesto sobre la partícula y presente en una cantidad de 0.5 a 10 por ciento en peso basado en el peso total del agente de soporte. El revestimiento polimérico incluye el producto de reacción de un copolímero de acrilato que comprende unidades de estireno y que tiene un número de hidroxilo de 20 a 500 mg de KOH/g o un valor de ácido de 20 a 500 mg de KOH/g, y una resina epoxi y/o una melamina.
