A series of siloxane poly(urethane‐urea) (SiPUU) were developed by incorporating a macrodiol linked with a diisocyanate to enhance mixing of hard and soft segments (SS). The effect of this modification on morphology, surface properties, surface elemental composition, and creep resistance was investigated. The linked macrodiol was prepared by reacting α,ω‐bis(6‐hydroxyethoxypropyl) poly(dimethylsiloxane)(PDMS)...
Mixed macrodiol based siloxane poly(urethane‐urea)s (SiPUU) having number average molecular weights in the range 87–129 kDa/mol were synthesized to give elastomers with high tensile and tear strengths required to fabricate artificial heart valves. Polar functional groups were introduced into the soft segment to improve the poor segmental compatibility of siloxane polyurethanes. This was achieved by...
