This chapter deals with a commercially very important part of the polyurethane (PU) polymer family, biodegradable polyurethanes (BioPUs). PUs are multiblock copolymers composed of a high molecular weight macrodiol, called a soft segment, and a hard segment composed of a diisocyanate and a low molecular weight diol. As a result of the thermodynamic incompatibility of
the hard and soft segments in PU copolymers the phenomenon of microphase separation occurs. Nowadays, it is generally accepted that the overall properties, as well as the biocompatibility, of segmented PU and poly(urethane urea) (PUU) copolymers are correlated to the degree of microphase separation. The thermoplastic and elastic behaviour of these copolymers can be
explained by their multiphase structure. The elastomeric properties of these copolymers are generally attributed to the phase separation of the hard and soft segments; the hard domains serve as crosslinks and reinforcing fillers in the matrix of the soft segm...ent. It is generally assumed that the soft phase is responsible for the reversible elasticity of the polymeric material, whereas the
hard phase is responsible for the mechanical strength properties.
