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

with double thermoresponsivity (in English)

Polimery 2013, No 9, 696


DOI: dx.doi.org/10.14314/polimery.2013.696

Summary

A copolymer showing two cloud points was obtained by grafting poly(N-isopropylacrylamide) (PNIPAM) onto hydroxypropylcellulose (HPC). The structure of the polymer was verified 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.


Key words: hydroxypropylcellulose, poly(N-isopropylacrylamide), thermosensitive polymer, cloud point, polymer-surfactant interactions, fluorescence probe
