    • A hydrous gel polymer prepared by polymerizing a monomer component containing acrylic acid (or a salt thereof) is post-neutralized so that each polymer particle derived from a polymer prepared by neutralizing the hydrous gel polymer has an acceptable degree of neutralization. Thereafter, the polymer prepared by neutralizing the hydrous gel polymer is reacted with a cross-linking agent reactive with the functional groups contained in the polymer. The acceptable degree of neutralization refers to, for example, a degree of neutralization which is at most 20 mol % lower than the average degree of neutralization of the agglomerate of the polymer particles or a degree of neutralization which exceeds at least 55 mol % of the average degree of polymerization of the agglomerate of the polymer particles. The post-neutralization is conducted so that, among 200 particles of the polymer, the number of polymer particles having an unacceptable degree of neutralization outside the obove range of the acceptable degree of neutralization is 10 or less. The water-absorbent thus prepared has a high absorption ratio under ordinary or high pressure, is reduced in the water-solubles content as compared with the conventional water-absorbent, and causes no significant change in the pH of swollen gel.
    • 通过聚合含有丙烯酸(或其盐)的单体组分制备的含水凝胶聚合物被后中和,使得衍生自通过中和含水凝胶聚合物制备的聚合物的每个聚合物颗粒具有可接受的中和度。 此后,通过中和含水凝胶聚合物制备的聚合物与与聚合物中包含的官能团反应的交联剂反应。 可接受的中和度是指例如比聚合物粒子的凝聚体的平均中和度低20摩尔%以上的中和度或超过聚合物粒子的至少55摩尔%的中和度 聚合物颗粒的附聚物的平均聚合度。 进行后中和,使得在聚合物的200个颗粒中,在可接受的中和度的超出范围之外具有不可接受的中和度的聚合物颗粒的数量为10以下。 如此制备的吸水剂在常压或高压下具有高吸收比,与常规吸水剂相比,水溶性物质的含量降低,并且不会引起溶胀凝胶的pH的显着变化。

    • A molding material composition comprising a resin composition such as an unsaturated polyester, a succinic acid derivative and a thickener such as magnesium oxide, wherein the water content is regulated to be within the range of 0.1 to 0.45 wt. %; and a molding material comprising the above composition and reinforcing fibers such as glass fibers and having a water content regulated to be within the range of 0.1 to 0.4 wt. %. The molding material composition is, as shown in the figure, reduced in initial thickening caused by the thickener, thus exhibiting excellent viscosity characteristics. Further, the composition is lowered in surface tackiness, though the viscosity of the composition after thickening is lower than that of the prior art. The composition has high fluidity and excellent impregnation properties, while it causes such a rapid viscosity increase after impregnation that it can be thickened in a time shorter than that of the prior art.
    • 包含树脂组合物如不饱和聚酯,琥珀酸衍生物和增稠剂如氧化镁的成型材料组合物,其中水含量被调节在0.1至0.45重量%的范围内。 %; 以及包含上述组合物的成型材料和玻璃纤维等增强纤维,其水分含量在0.1〜0.4重量%的范围内。 %。 如图所示,成型材料组合物由增稠剂引起的初始增稠减少,因此表现出优异的粘度特性。 此外,尽管组合物在增稠后的粘度低于现有技术,但组合物的表面粘性降低。 该组合物具有高流动性和优异的浸渍性能,而在浸渍之后其引起这种快速的粘度增加,使得其可以在比现有技术更短的时间内变稠。

    • An adsorbent and adsorbing method which enable a surfactant to be easily, inexpensively and satisfactorily recovered and removed from a surfactant-containing solution, such as waste water. Adsorbents usable herein include, for example, a cross-linked polymer having a polyoxyalkylene chain. The surfactant is adsorbed by bringing the adsorbent having the above constitution into contact with the solution. The cross-linked polymer is particularly preferably one prepared by cross-linking a polyalkylene glycol or one prepared by polymerizing a monomer component containing a (meth)acrylic ester monomer represented by the following general formula: CH2 = CR-CO-(X )n-Y wherein R represents hydrogen or methyl; X represents oxyalkylene having 1 to 5 carbon atoms; Y represents hydrogen, alkoxy having 1 to 5 carbon atoms, phenoxy, or oxyalkylphenyl having 1 to 3 alkyl groups with 1 to 9 carbon atoms as substituents; and n is a positive number of 8 to 100 on the average.

    • N-Cyclohexylmaleimide having a cyclohexylaminosuccinic anhydride content of 0.001 to 1 wt.% is used as the main raw material for the production of heat-resistant resins. The resins are produced by a process of copolymerizing the above material with at least one monomer copolymerizable therewith which is characterized by the use of a monomer having a low yellowness, the addition of a compound which can inhibit the evaporation of the non-radical compounds contained in the monomer through reactions, the addition of an antioxidant, the use of a solvent containing alcohol, or the presence of a non-radical-polymerizable acid anhydride or carboxylic acid. The heat-resistant resins produced by the use of the above raw material or the above process are excellent in transparency, i.e., less discolorable, even when an increased amount of N-cyclohexylmaleimide is used for the purpose of imparting more excellent heat resistance. Accordingly, the heat-resistant resins can be suitably used in the fields necessitating both a low discolorability and a high heat resistance.
