�� ObjectivesObjectives

To To reduce brittle behaviour reduce brittle behaviour of engineering of engineering polymers such polymers such as Polyesters, PA.as Polyesters, PA.

PET PET andand PBT have PBT have good mechanical and good mechanical and thermalthermal propertiesproperties ((flexural modulus flexural modulus etc.) but etc.) but theirtheir main main defects defects are the are the poor poor impact impact resistance at low temperatures resistance at low temperatures ((--30°C, 30°C, --40°C) 40°C) and sensitivity and sensitivity to to notch notch

�� SolutionSolution

To disperse To disperse homogeneously homogeneously in in small particlessmall particles an an elastomeric polymer elastomeric polymer ((low Tglow Tg) ) in the semiin the semi--cristalline Polyester cristalline Polyester matrix matrix in in order order to to reduce reduce the the brittle behaviorbrittle behavior by by a a mechanism which absorbs energy and avoidsmechanism which absorbs energy and avoids crack propagation crack propagation
