“…The linear aliphatic–aromatic polyesters poly(trimethylene terephthalate) (PTT) and poly(butylene terephthalate) (PBT) are industrially important in commercial fibers, polymeric films, and engineering plastics 1–9. PTT is polymerized from terephthalic acid [or dimethyl terephthalate (DMT)] and 1,3‐propanediol (1,3‐PD) 10.…”

The kinetics of the polycondensation and copolycondensation reactions of bis(3‐hydroxypropyl) terephthalate (BHPT) and bis(4‐hydroxybutyl) terephthalate (BHBT) as monomers were investigated at 270 °C in the presence of titanium tetrabutoxide as a catalyst. BHPT was prepared by the ester interchange reaction of dimethyl terephthalate and 1,3‐propanediol (1,3‐PD). Through the same method adopted for BHPT synthesis, BHBT was prepared with 1,4‐butanediol instead of 1,3‐PD. With second‐order kinetics applied for polycondensation, the rate constants of the polycondensation of BHPT and BHBT, k11 and k22, were calculated to be 4.08 and 4.18 min−1, respectively. The rate constants of the cross reactions in the copolycondensation of BHPT and BHBT, k12 and k21, were calculated with results obtained from proton nuclear magnetic resonance spectroscopy analysis. The rate constants during the copolycondensation of BHPT and BHBT at 270 °C decreased in the order k12 > k22 > k11 > k21, indicating that the reactivity of BHBT was larger than that of BHPT at 270 °C. © 2002 Wiley Periodicals, Inc.

There is a great interest in using micro and nano scale ingredients as fillers to create composites with enhanced physical properties. This thesis research explores the improvements these fillers offer with focus on combining both micro and nano ingredients to make multi-scale polymer composites. This investigation reveals the interplay of ingredient mixing, microstructural evolution, and processing conditions and characterizes the improvements of thermal and mechanical properties. This data is used to develop fundamental processing-structure-property relationships of these multi-scale composites across different concentrations of microscale and nanoscale ingredients and processing conditions in order to optimize their development.

“…Although these processes in relation to polyesters like PET and PBT were subjects of many studies [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], there are still some aspects which remain not exactly elucidated (e.g. mechanism of thermal and thermo-oxidative degradation).…”
