Abstract
Poly(alkylene terephthalate)s are frequently used polymers serving a plethora of applications, including packaging, textiles, and biomedical applications. However, their current synthesis procedures have some limitations, such as harsh reaction conditions and requirement of a catalyst. Furthermore, there is no control over the molar mass and only polymers with limited molar masses can be obtained. New optimized synthesis methods are therefore desired. To this end, we further improved our previously reported catalyst-free single-step solution polycondensation. By varying the comonomer ratio of both monomers, we gained control over the molar mass range and obtained polymers with number-average molar masses up to 187 kg/mol. Furthermore, by using a small excess of diol, we obtained polymers with alcohol end groups, allowing further functionalization. Finally, the melt recrystallization behavior for all investigated polymers was demonstrated using modulated differential scanning calorimetry. In conclusion, the synthesis method described in this paper circumvents the disadvantages of the current synthesis procedures.
