“…According to Nagai [19] who worked on thermolysis of a copoly(ether ester) and found a similar broadening of the peak at 1720 cm À 1 , this type of broadening effect is due to the formation of several types of carbonyl group, and he suggested that for this polymer the formation of aliphatic esters was responsible. www.scilet.com By analogy, for our experimental results, the following reaction mechanism for the thermal degradation is proposed as shown in Scheme 1.…”

Polyurethanes (PUs), produced by cross-linking with a di-isocyanate hydroxylated vegetable oils (rapeseed and sunflower), have been examined from the viewpoints of their thermal degradation and their materials properties, and how both of these aspects are influenced both by the addition of TiO 2 filler and by UV irradiation.The thermal decomposition of the PUs was investigated using thermal gravimetric analysis (TGA) and IR spectroscopy: the decomposition of a foam of the PU based on rapeseed oil showed complex kinetics, being apparently singlestage and of the first order at 973 K but with at least two separate stages at other temperatures. Thermolysis of PUs as films resulted in the production of carbonyl groups ( 1793 cm À 1 ) suggesting formation of an acid anhydride. Pyrolysis

To improve the low temperature elastic recovery and tensile properties of the traditional poly(ether ester), a series of randomly branched poly(ether ester)s consisting of poly(butylene isophthalate) as hard segment, poly(tetramethylene glycol) and poly(ethylene glycol) as mixed soft segment, and trimeth ylolpropane as trifunctional monomer were synthesized. The structure and composition of the samples were characterized by 1 H NMR and FTIR spectroscopy. The tensile strength, elongation at break and the low temperature elastic recovery were used to characterize the mechanical properties of the synthetic polymers.The results indicate that the branched poly(ether ester) showed an increment of mechanical and thermal properties with the increasing content of branching agent in the polymer matrix. Moreover, the low temper ature elastic recovery and tensile properties of branched poly(ether ester) were superior comparing to the tra ditional poly(ether ester)s.
