摘要： The present invention provides a composite resin composition comprises A) polypropylene-based resin by 100 weight portions, (B) organized denatured clay by 0.1 to 50 weight portions, and (C) maleic anhydride denatured polypropylene by 0.5 to 30 weight portions, in which the maleic anhydride denatured polypropylene satisfies the following conditions that the quantity of not-reacted maleic anhydride is outside a limit for quantitative analysis; that the percentage of acid content against a number of polymer chains is not less than 0.8 and not more than 2.0; that the molecular weight distribution is not less than 2.5; that the percentage of components with the molecular weight of 10,000 or less is not more than 0.5% by weight; and that the ultimate viscosity (η) is 1 or more. A supercritical gas is infiltrated in this composite resin composition for degassing to obtain resin foam. With the operations above, bubbles are formed finely and homogeneously at the high density and high solidity is provided.

摘要： Provided is an aromatic polycarbonate resin composition which comprises 100 parts by mass of an aromatic polycarbonate resin and from 0.001 to 1 part by mass of an additional thermoplastic resin that differs from the aromatic polycarbonate resin in the refractive index by at least 0.001 and which is so designed that the ratio (X)/(Y) is at least 0.5 wherein (X) indicates the spectral transmittance at 320 nm through a sample plate of the resin composition having a thickness of 2 mm and (Y) indicates the spectral transmittance at 633 nm through it. Having realized further increase in the transparency of aromatic polycarbonate resin, the resin composition gives moldings of which the transparency is comparable to that of acrylic resin for optical use, and the resin moldings have good impact resistance and heat resistance.
摘要翻译：提供一种芳香族聚碳酸酯树脂组合物，其包含100质量份芳族聚碳酸酯树脂和0.001〜1质量份的另外的热塑性树脂，其折射率不同于芳族聚碳酸酯树脂至少0.001，设计为（X）/（Y）的比例至少为0.5，其中（X）表示通过厚度为2mm的树脂组合物的样品板在320nm处的光谱透射率，（Y）表示在633处的光谱透射率 nm通过它。实现了芳族聚碳酸酯树脂的透明度的进一步提高，树脂组合物赋予了与光学用丙烯酸树脂相当的透明度的模塑品，并且树脂模制品具有良好的耐冲击性和耐热性。

摘要： The present invention relates to a polycarbonate resin that has a viscosity average molecular weight of from 10,000 to 17,000 and has characteristic features in an iron content, a free total phenol content, a content of a releasing agent, a fraction of hydroxyl end groups, a 1 H-NMR spectrum or the like. The polycarbonate resin has less defects due to flash without increase of an addition amount of a releasing agent to an unnecessary level and therefore is suitable for a material of an optical disk substrate.
摘要翻译：本发明涉及粘度平均分子量为10,000〜17,000的聚碳酸酯树脂，其特征在于铁含量，游离总苯酚含量，脱模剂含量，羟基端基的分数， 1 H-NMR光谱等。聚碳酸酯树脂由于闪光而具有较少的缺陷，而不会使脱模剂的添加量增加到不必要的水平，因此适用于光盘基材的材料。
