    摘要: Catalyzed processes for the preparation of aliphatic di- and polyurethanes from aliphatic di- or polyamines, urea, and monofunctional, aliphatic alcohols are disclosed which result in shorter reaction times and/or higher yields than the corresponding uncatalyzed reactions.This is a continuation-in-part of U.S. Application Ser. No. 124,701 filed Nov. 24, 1987, now abandoned, which is a continuation in part of Ser. No. 135,247, filed Mar. 31, 1980, now abandoned, and Ser. No. 879,025 filed June 26, 1986, now U.S. Pat. No. 4,713,476 both applications claiming priority to Federal Republic of Germany application No. 2917493, filed Apr. 30, 1979, which are herein expressly incorporated by reference.
