Application of poly(N‐isopropylacrylamide) with pendent β‐cyclodextrin to separation of a guest substance in an aqueous solution

Abstract

Poly(N-isopropylacrylamide) with pendent p-cyclodextrin (PNI-PAAm-CD) was prepared by copolymerization of acyloyl-p-CD and NlPAAm. During the temperature-induced phase separation of an aqueous solution of PNlPAAm-CD, Toluidine Blue dye in the solution was separated into the precipitate of PNlPAAm-CD by way of inclusion complex formation.
