ABSTRACT:
A high flow polyester composition is disclosed, which comprises at least one polyester and at least one flow enhancing ingredient of structure, I,where, R1=NH2or CH2OH; R2=CH3, CH3CH2or CH2OH or any of C1-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.
