Beschreibung
Zusammenfassung:	The present invention relates to. a process for preparing isosorbide containing polyester polymer using antimony and inorganic tin catalyst system, wherein isosorbide is incorporated as a comonomer. The present invention also relates to an isosorbide containing polyester polymer wherein isosorbide is incorporated as a comonomer and process for its preparation using said catalyst system. The invention also relates to a process which results in improved colour and improved polymerization rate (melt / solid-state) having significant importance in end-use applications.
