Abstract

Procedure for the manufacture of polyalkene terephthalate The invention concerns a procedure for the manufacture of polyalkene terephthalate, in which both the transesterification and the polycondensation steps are performed with one and the same catalyst. According to the invention, hydrotalcites and hydrotalcite-like compounds of general formula [M(II)1-xM(III)x(OH)2]?x+(An-x/n).m H2O are used alone or in combination with suitable stabilizers, for instance phosphorus compounds or derivatives of ortho-tert.-butyl-phenol, without requiring deactivation of the transesterification catalyst. The M(II) in the general formula stands for divalent metals, in particular for magnesium, zinc, nickel, copper, iron(II) or cobalt(II). M(III) are trivalent metals, for instance aluminum or iron(III). A are anions, such as carbonates, borates or titanyl compounds.
