ABSTRACT:
Novel polymers of general formula: ##STR1## wherein R is an alkyl or aryl group that contains an active hydrogen atom (as determined by the Zerewitinoff test); A is a spacing group having at least one carbon atom; B is a spacing group having at least two carbon atoms; and R and R' are alkyl or aryl groups. The polymer is synthesized via the Mannich pathway, involving formation of an imine intermediate.
