| titleOfInvention | Polyurethane sheet material of low discoloration |
| abstract | PURPOSE: To obtain a sheet material of low discoloration, by applying a solution of a specified polyurethane elastomer to a base and forming it into a film of a porous structure by a wet coagulation process. n CONSTITUTION: The following polyurethane elastomer solution is applied to a base and formed into a film of a porous structure by a wet coagulation process to form a sheet meterial. Said polyurethane elastomer is one obtained by reacting a polyol with 70W95mol%, based on the polyol, diphenylmethane 4,4'-diisocyanate and reacting the product with 5W30mol%, based on the polyol, nonaromatic diisocyanate. The porous structure of this sheet material is formed in such a way that the solvent of the polyurethane elastomer solution is dissolved in a coagulant during coagulation, the places are filled with the coagulant and the whole is coagulated while the places survive as pores. The size of a cell at this time can be varied freely by selecting the resin concentration of a solution, the composition of a coagulant, a coagulation bath temperature, and a coagulation aid, and a size of a cell of about 10W1,000μ is adopted. n COPYRIGHT: (C)1985,JPO&Japio |
