Abstract: A process of preparing an aqueous solution of a cycloimide-containing polymer includes heating an aqueous solution of a cycloanhydride-containing polymer with a first neutralizing agent at a ratio of cycloanhydride to neutralizing agent of about 1 : 1 to about 1 : 1.5 at a temperature and for a time sufficient to form the aqueous solution of the cycloimide-containing polymer having a cycloimide to acid group ratio of about 1 :2 to about 1.5:2.

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。
