    • A high flow polyester composition is disclosed, which comprises at least one polyester and at least one flow enhancing ingredient of structure I

      where, R 1 = NH 2 or CH 2 OH; R 2 = CH 3 , CH 3 CH 2 or CH 2 OH or any of Cl-C20 alkyl group which may have one or more hydroxy group substituent, C3-C20 cycloalkyl group, C6-C20 aryl group, C1-C20 alkoxy group which may have one or more hydroxy group substituent or C6-C20 aryloxy group. A good balance of flowability and mechanical properties is obtained by controlling the amount of the said flow-enhancing ingredient. The composition further comprises reinforcing fillers, impact modifiers, a property-enhancing thermoplastic such as polycarbonate and flame retardant chemicals. The compositions are suitable for making automotive, electric and electronic parts.
