摘要： The present invention provides a cellulose acetate satisfying at least one requirement selected from the following requirements (A) , (B) and (C), provided that the case where (B) alone is satisfied is excluded.
Requirement (A) : Bright spotty matters in sizes of 20 µm or more are not more than 20 units/mm 3 .
Requirement (B) : Blocking constant (K) is not more than 60.
Requirement (C): The ratio (G'/G") of storage modulus (G') to loss modulus (G") at a measuring frequency of 0.016Hz is not more than 0.2.摘要翻译： 本发明提供满足以下要求（A），（B）和（C）中至少一个要求的乙酸纤维素乙酸酯，只要满足（B）单独满足的情况即可。 要求（A）：尺寸为20亩以上的亮点不大于20单位/ mm 3。 要求（B）：阻塞常数（K）不大于60.要求（C）：测量频率为0.016时储能模量（G'）与损耗模量（G“）的比值（G'/ G”） Hz不大于0.2。

摘要： The present invention is to provide a method of producing a separating agent for an enantiomeric isomer having high optical resolution power together with sufficient solvent resistance. That is, a method of producing a separating agent for an enantiomeric isomer comprising the steps of allowing the porous carrier to carry the optically active polymer compound by bringing the porous carrier into contact with a dope of the optically active polymer compound; and exposing a product to radiation.
