Abstract
The glass transition behavior of poly(α-methyl styrene), its tridecamer, and an athermal blend with its hexamer is investigated using differential scanning calorimetry. The glass transition, Tg, of the blend is found to become broader than that of the pure materials. However, the absolute heat capacity of the blend remains unchanged. The length scale of the cooperatively rearranging regions of the samples, as well as previously studied pentamer, polymer, and blends, is estimated from Donth's fluctuation model. The broadening of Tg is found to accompany a decrease of the length scale. In addition, the correlation between Tg, fragility, and the length scale of CRR is also examined.
