Popis:	Biodegradable polyurethane urea (PUU) elastomers are ideal candidates for fabricating tissue engineering scaffolds with mechanical properties akin to strong and resilient soft tissues. PUU with a crystalline poly(e-caprolactone) (PCL) macrodiol soft segment (SS) showed good elasticity and resilience at small strains (
