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 translation: 当与通过常规高温方法制备的常规苯乙烯（甲基）丙烯酸低聚物相比时，在比常规固体级低聚物更低的温度下制备或者被氢化的苯乙烯类（甲基）丙烯酸类低聚物包含更少的末端乙烯基不饱和度。 与常规和非氢化苯乙烯（甲基）丙烯酸低聚物相比，包含较少末端乙烯基不饱和度的苯乙烯类（甲基）丙烯酸类低聚物表现出改善的热稳定性并且可以提供改进的耐紫外线老化性。

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 incluye una partícula presente en una cantidad de 90 a 99.5 por ciento en peso y un revestimiento polimérico dispuesto alrededor de la partícula y presente en una cantidad de 0.5 a 10 por ciento en peso, basándose en el peso total del agente de soporte. El revestimiento polimérico incluye el producto de reacción de un copolímero de acrilato y un isocianato. El copolímero de acrilato incluye unidades de estireno y tiene un índice de hidroxilo de 20 a 500 mg KOH/g. Un método para formar el agente de soporte incluye las etapas de combinar el copolímero de acrilato y el isocianato para hacer reaccionar y formar el revestimiento polimérico y revestir la partícula con el revestimiento polimérico para formar el agente de soporte.

Abstract: Oligómeros (met)acrílicos estirénicos que se preparan a una temperatura más baja que los oligómeros de grado sólido convencionales, o son hidrogenados, contienen menos insaturaciones vinílicas terminales, cuando se comparan con los oligómeros (met)acrílicos estirénicos convencionales preparados por los procesos de alta temperatura de costumbre. Los oligómeros (met)acrílicos estirénicos que contienen menos insaturaciones vinílicas terminales demuestran estabilidad térmica mejorada y pueden proveer resistencia mejorada a UV en comparación con los oligómeros (met)acrílicos estirénicos convencionales y no hidrogenados.
