Title:
TEMPERATURE-RESPONSIVE ADSORBENT HAVING STRONG CATION EXCHANGE GROUP, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/081727
Kind Code:
A1
Abstract:
Provided is a temperature-responsive adsorbent wherein a copolymer that contains at least N-isopropylacrylamide is immobilized on the surface of a base. The copolymer has at least a strong cation exchange group. In addition, the copolymer contains the strong cation exchange group in an amount of 0.01-5 mol% relative to N-isopropylacrylamide in terms of monomers.
