Title:
ラクトン含有高分子量化合物の分離方法
Document Type and Number:
Japanese Patent JP3925198
Kind Code:
B2
Abstract:
A method for separating a lactone-containing high-molecular weight compound comprising subjecting a mixture of a lactone-containing high-molecular weight compound having, as its side-chain, at least one of a lower alkenyl group and a lower alkoxy group and its analogous compound(s) to either one or both steps in any order of a step (A) for adsorbing the mixture to a nonionic adsorption resin and eluting with an aqueous solvent containing silver ions, and a step (B) for adsorbing the mixture to a basic active alumina and eluting with an organic solvent to separate each of the compounds.
