In the present study, three new biobased furanoate polyesters with potential use in food packaging applications, named poly(isosorbide furanoate) (PIsF), poly(methyl-propylene furanoate) (PMePF) and poly(1,4-cyclohexane-dimethylene 2,5-furanoate) (PCHDMF) were synthesized. As monomers for the preparation of the polyesters, 2,5-furandicarboxylic acid (FDCA) and diols with irregular or complicated structure were used, including isosorbide (IS), 2-methyl-1,3-propanediol (MPD) and 1,4-cyclohexane-dimethanol (CHDM). The polymerization process was carried out via melt polycondensation method. The structural characteristics and thermal behavior of the polymers were studied. The kinetic fragility of the amorphous phase of the polymers was evaluated. The thermal degradation was studied by means of thermogravimetry and a pyrolysis Py-GC/MS (Pyrolysis-Gas Chromatography/Mass Spectroscopy) system to estimate the degradation mechanism.
在本研究中,合成了三种具有潜在食品包装应用价值的新型生物基呋喃酸聚酯,分别命名为聚异山梨醇呋喃酸酯(PIsF)、聚甲基丙烯呋喃酸酯(PMePF)和聚(1,4-环己烷二甲醇2,5-呋喃酸酯)(PCHDMF)。作为制备聚酯的单体,使用了2,5-呋喃二甲酸(FDCA)和结构不规则或复杂的二醇,包括异山梨醇(IS)、2-甲基-1,3-丙二醇(MPD)和1,4-环己烷二甲醇(CHDM)。聚合过程通过熔融缩聚法进行。研究了聚合物的结构特征和热行为。评估了聚合物非晶相的动力学脆性。通过热重分析法和热解Py-GC/MS(热解气相色谱/质谱)系统研究热降解,以估计降解机理。
