Effect of cyclodextrins on pH-induced conformational transition of poly(methacrylic acid)
Original language description
A pH-induced conformational transition (CT) of atactic poly(methacrylic acid) (PMMA) from the contracted to expanded conformation was investigated by viscometry, potentiometric titration, and anthracene solubilisation in the presence of - glucose, ?-cyclodextrin (?CD), and ?-cyclodextrin (?CD), respectively. No effect of glucose and ?CD on CT was observed. On the other hand, the CT characteristic features were absent in the presence of ?CD. The different effects of the co-solutes indicate that the interaction between PMAA and ?CD corresponds to the partial inclusion of the PMAA chain into the ?CD cavity. The viscometry and anthracene solubilisation imply that ?CD promotes the expanded conformation of PMAA at low pH. The potentiometric behaviour corresponds to that of the contracted PMMA conformation. Thus the results suggest the hierarchical picture of the PMAA conformation at low pH in which the local arrangement of the PMAA chain is a prerequisite for clustering on a larger scale.
