The present disclosure relates to a process for preparing polyester. The process for preparing the polyester essentially involves the preparation of the isosorbide oligomer and the isosorbide polymer from the isosorbide oligomer. The isosorbide oligomer or isosorbide polymer is then co-polymerized with the polyester. The copolymerization isosorbide oligomer or isosorbide polymer may be carried out at any stage of the preparation of the polyester. The polyester obtained in accordance with the process of the present disclosure can be used in packaging applications such as preparing packaging materials or containers. The material or container obtained from the polyester of the present disclosure is capable of withstanding a temperature of 60 to 90° C. without undergoing any deformation and shrinkage. Further, the material or container obtained from the polyester of the present disclosure is transparent or has lower color b* value.
