摘要 |
A porous sheet is obtained by wet coagulating a polyurethane comprising a soft segment component of repeating units from a polycarbonate, those from a diethylene glycol-based polyester and those from a tetramethylene glycol-based polyester and a hard segment component of an aromatic diisocyanate and ethylene glycol. The polyurethane has excellent processability such as wet coagulatability and the obtained porous sheet has good durability and flexibility, in particular flexibility at low temperatures and is well usable for leather-like sheets.
