摘要: Abstract Detailed analysis of current theoretical approaches and empirical correlations between the KWW stretching exponent β molecular structure single-component polymer systems suggests that values for structural relaxation in glass transition range change continuously with kinetic free volume fraction f g k , rather than are fixed at `universal' value =3/7.
