Popis: Open-chain polymeric Reisert compounds, i.e., poly[α-(acylamino)nitrile]s, can be prepared by condensation of bi(α-aminonitrile)s with adipoyl chloride. When the bis(α-aminonitrile) possesses hindered internal secondary amine groups, no high molecular weight polymers could be obtained. From less hindered bis(α-aminonitrile)s amorphous polymeric Reissert compounds of intrinsic viscosity 0.15-0.24 dL.g -1 were synthesized. Their stability was found to exceed in most cases 350°C in nitrogen (5% weight loss). By virtue of the Reissert moiety's acidic proton, chemical modification of such polymers, e.g. by alkylation, provides a means of bulk and surface property control
