Abstract
AbstractThe Raman spectra of solutions of poly(N‐vinyl‐2‐pyrrolidone) (PVP; M̄w = 1 000, 10 000, 40 000 and 360 000) in D2O and dimethyl sulfoxide (DMSO) were measured at various concentrations. PVP is hydrated by D2O in a manner different from N‐ethyl‐2‐pyrrolidone (NEP) and N‐methyl‐2‐pyrrolidone (NMP), monomer analogues of PVP. The self‐association of DMSO molecules in the solution of PVP was found to be different from that in the solution of NMP by using difference spectroscopy. These phenomena were attributed to a net‐like structure of concentrated solutions of PVP.
