Polymerization of N-isopropylacrylamide (NIPAAm) was performed in the presence of P-cyclodextrin (B-CD) [or hydroxypropyl-/3-cyclodextrin (HOP-P-CD)]. The formation of an inclusion complex between PNIPAAm and p-CD was confirmed by FT-IR, 'H N M R and 2D-NOESY NMR. It was found that the cloud point (
The effects of both anionic (sodium dodecyl sulfate, SDS) and cationic (dodecylpyridine bromide, DPB) surfactants on the phase transition of narrowly distributed poly(N-isopropylacrylamide) (PNIPAM) microgel particles were investigated by laser light scattering. The addition of SDS swells the partic
Poly(N-isopropylacrylamide) (PNIPAM) is well known to exhibit reentrant behavior or cononsolvency in response to the composition of a mixed solvent consisting of water and a low-chain alcohol. Since the solvent structure plays an important role in this phenomenon, the presence of structure-breaking/
