Poly(trimethylene phthalates or naphthalate) and copolymers are aromatic polyesters made by polycondensation of 1,3-propanediol (PDO) and terephthalic acid (PTT), isophthalic acid (PTI) or naphthalic acid (PTN) and/or with comonomers (isophthalic acid, 1,4-butanediol, etc.). This presentation describes the chemistry and properties of such PDO based polyesters and their applications in films and packaging. Key performance properties of the several PDO based polyesters including poly(trimethylene naphthalate) will be compared with poly(ethylene terephthalate), poly(ethylene naphthalate) and nylon 6.
