    Abstract: A proppant comprises a particle present in an amount of from 90 to 99.5 percent by weight based on the total weight of the proppant, 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 comprising styrene units and having a hydroxyl number of from 20 to 500 mg KOH/g or an acid value of from 20 to 500 mg KOH/g, and an epoxy and/or a melamine.

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: 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: 当与通常的高温工艺制备的常规苯乙烯(甲基)丙烯酸低聚物相比时,在比常规固体级低聚物低的温度下制备或被氢化的苯乙烯(甲基)丙烯酸低聚物含有较少的末端乙烯基不饱和度。 含有较少末端乙烯基不饱和基团的苯乙烯(甲基)丙烯酸低聚物表现出改善的热稳定性,并且与传统和非氢化苯乙烯(甲基)丙烯酸低聚物相比,可提供改善的抗紫外线风化性能。
