Same trends have been recently observed in the literature. A decreased of Tg of 77 °C was obtained with 30 wt% aliphatic polyesters with unprotected chain ends with PVC . A recent study showed that it is possible to adjust the plasticizing effect and therefore the Tg of materials, by playing on the length of the alkyl chain grafted onto polyester chain ends . For example, Tg values below 30 °C have been achieved with alkyl chain ends with 8 or 12-carbons. Indeed, the OH groups at the end of the PHO-diol chain may tend to form aggregates due to the hydrogen bonds formed between plasticizer molecules. As a result, PHO-diol may be poorly distributed in PVC, reducing the efficiency of the plasticizing effect. Thus, the alkyl chain ends of PHO-hexyl would enable better dispersion in the matrix, beyond the increase in free volume. Uniaxial tensile tests were also carried out to determine the evolution of E and εmax of formulations containing PHO-hexyl and DPHP:DIDP. The results are reported in Figure . All values for plasticized PVCs are similar, indicating a similar plasticizing effect between phthalates and the sustainable additive. Moreover, σmax and E were at least divided by 6 and 13, respectively, compared to neat PVC values. The plasticization effect reduces the rigidity of materials and thus lowers E and thus σmax. As a result, σmax increased by a factor of at least 12, confirming the plasticizing effect of these molecules.
