摘要
A thermoplastic polyurethane elastomer (TPU) composition which comprises: a) a poly(trimethylene carbonate) diol (PTMC diol) as the soft segment; b) a diisocyanate; and c) at least one glycol which reacts with the diisocyanate to form the hard segment which comprises from 10 % to 55 % by weight of the composition wherein the hard segment is defined as the sum portion of diisocyanate that reacts with the glycol plus the unreacted glycol.
