Below the melting region it is found that ΔL/L-T curves for solution-cast films show the same normal thermodynamic thermal changes, as are found in linear expansion regarding, for example, first and second order transitions and crystallization. But those for melt-cast films show the heat relaxation of internal stress caused by casting besides normal thermal changes.
Data of expansion co-efficient and transition temperature are listed in a table.
