Abstract

The present invention relates to polyester urethanes comprising polypentadecalactone segments. These polyester urethanes do show good properties which may be adjusted in a controlled manner. In preferred embodiments the polyester urethanes display additionally polycaprolactone segments. Such polymer may show shape memory effects.
