MULTIBLOCK-COPOLYMER AQUEOUS SOLUTION COMPOSITION WITH IMPROVED-STABILITY

摘要

The present invention relates to: an aqueous solution composition wherein the stability of the sol state of a multiblock-copolymer having sol-gel transition characteristics can be improved; and a stabilisation method therefor. More specifically, the present invention relates to: a multiblock-copolymer aqueous solution composition for refrigerated storage, which comprises a multiblock copolymer dissolved in distilled water or a buffer solution, and in which the multiblock copolymer has a molecular weight reduced by no more than 30% when stored for 2 years; and a stabilisation method therefor.
