Differential scanning calometry

PPS substituted with methoxy, acetyl, and hydroxy groups were analyzed by Laakso et al. [102-104]. The introduction of methoxy- and acetylgroups also increases the molecular weight and lead to higher conductivity. Blends, blocks, and statistic copolymers of 1,4-phenylensulfide with 2-methyl-1,4-phenylensulfide have been synthesized and their thermal behavior was examined by differential scanning calometry (DSC) [96]. 

Differential scanning calometry, DSC, curves of P30T show one low temperature transition at -20°C corresponding to the glass transition temperature,Tg, and one high temperature transition at 165°C corresponding to melting of the polymer.
