Abstract
Polymer blends having improved torque transmitting properties are disclosed. The polymer blends include polyetherurethane and a concentration of polyetherester sufficient to provide the polymer blend with a 37.degree. C. dynamic torque value greater than 40% of the polymer blend's 25.degree. C. dynamic torque value. The polymer blend can be thermally processed to form small diameter tubing suitable for general purpose catheters requiring both a high degree of maneuverability and sufficient resiliency to avoid tissue perforation.
