Elastomers containing polyamide groups and polyurea groups in bonded form, as well as a process for the preparation of elastic, non-cellular molded articles from these elastomers

Abstract From the Canadian patent

Abstract, The subject of this invention is elastomers containing polyamide groups and polyurea groups in bonded form which are, prepared by the reaction of a) at least one organic polyisocyanate and/or a modified polyisocyanate mixture having an NCO content of from 8 to 33.6 weight percent b) at least one polyazomethine and, c) at least one alkyl-substituted aromatic polyamine having a molecular weight up to 500, in the presence of or in the absence of d) catalysts, whereby reaction products of polyoxyalkylenepolyamines having a, functionality of from 2 to 4 and an average molecular weight of from 180 to 10,000 and at least one organic aldehyde and/or preferably ketone, are used as the …
