Abstract:
A process of preparing a modified polyalkylene terephthalate by melt polycondensation comprising reacting an alkylene diol and polyethylene terephthalate, wherein polymerization occurs in the presence of a catalyst complex formed by reaction of tetra(alkyl) titanate and a compound selected from phosphorus-containing compounds, nitrogen-containing compounds, boron-containing compounds, and combinations thereof.
