HLS/PVA blends show a single compositional dependent Tg
over the entire blend ratio, which obviously rise gradually from
74.9 ◦C to 103.5 ◦C. This single Tg strongly indicates that HLS/PVA
blends show miscibility on a dimensional scale between 5 and
15 nm. The dependence of a single Tg on the proportion of individual components was illustrated in Fig. 2. It is demonstrated that
this Tg versus composition do not obey either Fox, Couchman or
Gorden–Taylor relationships, but it could be well fitted by Kwei
