Abstract
In accordance with the present invention, it has now been found that the coagulation property of polyurethane elastomers can be considerably improved without spoiling any desirable chemical property of the original elastomer, if polyurethane elastomers which are different only in N%, are mixed together in a specified range of mixing ratio or if a polyurethane elastomer is synthesized using a mixture of polymer glycols whose structural units are chemically the same, however, whose molecular weights are different from each other in a specified range, and a solution of the obtained elastomer is coagulated by a specified wet coagulation condition.
