“…It has been demonstrated that the presence of functionalizable groups, such as hydroxyl and carboxylate, in polyesters can efficiently increase their hydrophilicity and degradability, plus modulate their mechanical, thermal, chemical, and biological properties (Lecomte et al, 2006;Parrish and Emrick, 2006;Williams, 2007). Within the new group of degradable polymers, various types of aliphatic polyesters films have been described (Bayer et al, 2004;Benitez et al, 2004;Olsson et al, 2007;Heredia-Guerrero et al, 2009;Quinzler and Mecking, 2010;Stempfle et al, 2014;Benítez et al, 2015). Between them, successful polycondensation reactions have been achieved using titanium alkoxides as catalyst to afford the corresponding longchain aliphatic polyesters (Quinzler and Mecking, 2010;Stempfle et al, 2014).…”
