Polyurethanes prepared from amide linkages-containing diamine chain extender |
摘要 |
Polyurethane elastic products prepared by a two-stage process are disclosed. In the first stage, polyols are reacted with diisocyanates to form prepolymers. The prepolymers are then reacted with diamine chain extenders which contain amide linkages, to form polyurethane elastic products.
