摘要： An unsaturated polyester resin composition is prepared by blending an unsaturated polyester resin having a hydrogenated bisphenol skeleton with a shrinkage lowering agent comprising a three-dimensional styrene polymer and a viscosity depressant. This composition is inhibited from shrinkage both in curing and in cooling after molding. Thus, the composition can give molded articles excellent in surface smoothness, gloss and so on.
摘要翻译：通过将具有氢化双酚骨架的不饱和聚酯树脂与包含三维苯乙烯聚合物和降粘剂的收缩降低剂共混来制备不饱和聚酯树脂组合物。该成分在成型后的固化和冷却中被抑制。因此，组合物可以赋予表面平滑性，光泽度等优异的成型体。

摘要： Provided is a particulate water-absorbent agent having suppressed reduction of absorption capacity, after elapse of a long time, good gel layer diffusion performance and reduced Re-wet, a water-absorbent goods containing the water-absorbent agent, and a production method for the water-absorbent agent. The above problem is solved by a particulate water-absorbent agent having a polyacrylate salt-type water-absorbent resin as a main component, and having an absorption capacity without load of equal to or higher than 28 g/g, characterized by satisfying the following (a) to (c):
(a) amount of water-soluble component under stirring is from 15 to 60% by mass;
(b) difference between an amount of water-soluble component under stirring and an amount of water-soluble component in standing still (amount of water-soluble component under stirring - amount of water-soluble component in standing still) is from 15 to 50% by mass; and
(c) diffusion absorption index is from 1.40 to 10.0 g/g/min;
wherein the amount of water-soluble component under stirring represents amount of a dissolution polymer after 16 hours, to a normal saline solution under stirring, and the amount of water-soluble component in standing still represents amount of a dissolution polymer after 16 hours, to a normal saline solution in standing still.
