**Abstract**
 The properties and characteristics of segmented polyurethane elastomers and polydimethyl siloxane (PDMS) are described. In this work, PDMS monomer was incorporated into the soft segment of polyurethane using a stepwise reaction between at least two bifunctional compounds (4,4'-diphenylmethane diisocyanate, hydroxyl-terminated PDMS and 1,4-butanediol) to improve the thermal properties of a typical PU. The phase transition and degradation characteristics of the poly(urethane-siloxane) copolymers were studied using DSC and TGA. 32 refs.
