Vereinigte Glanstoff Fabriken AG were granted early patents on the methanolysis of polyester melts [206, 207]. The polymer is mixed with a transesterification catalyst or sprayed therewith in finely divided molten droplets, and treated with superheated methanol in a sealed chamber. Societa Italiana Resine SpA carry out the process in the presence of acid catalysts [208]. Rhone-Poulenc use magnesium methylate as a catalyst [209]. The process claimed by Cudmore has finely divided PET slurried in aqueous methanol depolymerised at high temperature and pressure, with DMT recovery by flash crystallisation [210]. [Pg.118]
