| Abstract
| - Poly(styrene-b-butyl methacrylate) diblock copolymers, PS-b-PBMA, with different morphologies are investigated with respect to the influence of strain rate and temperature on tensile properties.In the first part the mechanical properties of bicontinuous and perforated lamellar structure are comparedwith other morphologies. Diblock copolymers with bicontinuous structures (39% PS) show a much highertensile strength as well as a higher strain at break than diblock copolymers with lamellar structures(50% PS). In the second part the dependence of tensile properties on strain rate and temperature arediscussed for different morphologies. A diblock copolymer with a polystyrene content of 76% PS revealshexagonally packed PBMA−cylinder, and the tensile strength, strain at break, and Young's modulusexceed the values of pure polystyrene at all measured strain rates. The interesting properties of PS-b-PBMA diblock copolymers are discussed with respect to the phase behavior, interface formation, andchain conformation.
