Abstract

poly(trimethylene terephthalate) (PTT) was synthesized via condensation polymerization using different molar ratios of 1,3-propane diol (PDO)/terephthalic acid (TPA) in the presence of tetraisopropyl titanate (TiPT) as a polyesterifi-cation catalyst. The effect of reaction conditions on the characteristics of as-polymerized PTT was investigated.
