PROCESS FOR THE PRODUCTION OF POLYAMIDE FOAMS AND ELASTOMERS FROM AMINO-CROTONIC ACID ESTERS

Novel polyamides are obtained by a process which comprises the polyaddition of aliphatic or aromatic polyisocyanates with N-substituted-amino-crotonic acid esters. The addition of the NCO group takes place on the active hydrogen atom of the GROUP OF THE AMINO-CROTONIC ACID ESTER.
