摘要：

The melting and crystallization behaviour of blends of poly(ethylene oxide) and poly(vinyl alcohol) has been analysed. Hoffman-Weeks plots of the observed melting points versus crystallization temperatures are constructed. From these plots, melting-point depressions have been found. However, measurements of glass transition temperatures by dynamic mechanical thermal analysis have shown no changes for poly(ethylene oxide). Crystallization kinetics became slower as the poly(vinyl alcohol) content was increased.
