Hydroxypropylcellulose-graft-poly(N-isopropylacrylamide) — novel water-soluble copolymer with double thermoresponsivity

摘要

Acopolymer showing two cloud points was obtained by grafting poly(Nisopropylacrylamide)ud(PNIPAM) onto hydroxypropylcellulose (HPC). The structure of the polymer wasudverified using 1H NMR, FT-IR, GPC, and elemental analysis. The values of cloud points could be changed by increasing ionic strength and as a result of the interactions with surfactants.
