Determination of the cooperativity parameter σ from viscometric data of poly-L-glutamic acid-Na

Polymer Bulletin Aims and scope Submit manuscript

Summary

Viscometry of PLGNa solutions was performed for various degrees of neutralization α. The cooperativity parameter σ in the helix-coil transition was estimated using Ptitsyn's method with some modifications. The increase of σ thus obtained with decreasing α is explained in terms of the a dependence of short-range interactions of PLGNa segments.
