Abstract

1286755 Polyethylene terephthalate M & T CHEMICALS Inc 24 June 1970 [24 June 1969] 30712/70 Heading C3R In the manufacture of polyethylene terephthalate from terephthalic acid or its dimethyl ester and ethylene glycol, there is used as a polycondensation catalyst, a sulphurcontaining organoantimony compound of formula (R 2 Sb) 2 S; RaSb(SR) 3-a ; R a Sb(OR<SP>1</SP>SH) 3-a RaSb(OOCR<SP>1</SP>SH) 3-a ; or wherein R and R<SP>1</SP> are hydrocarbon radicals which may be inert by substituted, R<SP>11</SP> is a hydrocarbon radical which may be inertly substituted or a hydrogen atom and a is 1, 2 or zero. In the examples polyethylene terephthalate is prepared using antimony-5,5<SP>1</SP>,5<SP>11</SP>-thiophenate, antimony-S,S<SP>1</SP>,S<SP>11</SP>-thiobenzoate, antimony tris-isooctylmercaptoacetate and antimony tris-N,N-diethyldithiocarbamate as polycondensation catalysts.
