Poly trimethylene terephthalate
WebPoly(trimethylene terephthalate) (PTT) was first synthesised and patented in 1941 (Whinfield and Dickson, 1941) but was not produced commercially due to the expense of one of the precursors, 1,3-propanediol (PDO) . The production of PDO was halted in the mid-1960's and ethylene oxide (EO) hydroformulation was developed as an alternative. WebMay 1, 1979 · The structure of poly (trimethylene terephthalate) The determination of the crystalline structure of oriented fibres of poly (trimethylene terephthalate) is described. The unit cell is triclinic with the following parameters: a = 4.6 A, b = 6.2 A, c = 18.3 A, α = 98°, β = 90°, γ = 112°. Each cell contains two monomers of one polymer chain.
