New cross-linked poly(ester-siloxane)urethanes were prepared by multistep polyaddition from aromatic diisocyanates and diglycerin maleate, as the hard segment, and poly(ethylene glycol adipate) or poly (diethylene glycol adipate) and poly(dimethyl siloxane), as the soft segment. In some cases the soft segment was extended with polybutadiene segments. The influence of structure and position across the chain of the hard and soft containing segments upon mechanical and thermal properties were studied using thermogravimetric and mechanical techniques.
