抄録

Segmented polyurethanes (SPU) and poly(urethane-urea)s (SPUU) were synthesized from lysine based diisocyanate (LDI), polycaprolactone diol (PCL), and 1,3-propanediol (PDO) or 1,4-butanediamine (BDA). DSC thermogram of SPU and SPUU showed that the glass transition temperature (Tg) of BDA-based hard segment is higher than that of PDO-based one. WAXD and SAXS of SPU and SPUU revealed the aggregation states of hard and soft segments. Furthermore, the degradation behavior was investigated by exposing the polymers to a buffer solution at 310 K (pH=7.6) and activated sludge. The higher degradation rate in activated sludge compared with that in a buffer solution means the biodegradation of these SPU and SPUU.
