Abstract
An oligomer of trans-2, 5-dimethyl piperazine oxamide containing amino terminal groups was synthesized as a precursor of block copolymers characterized by moisture regain properties.
A low temperature solution polymerization method was applied using trans-2, 5-dimethyl piperazine and oxalyl chloride. In order to attain the desired degree of polymerization, a solvent was used in such a way that polydimethyl piperazine oxamide precipitated as the polymerization proceeded. The expected oligomer containing amino terminal groups was obtained by using excess trans-2, 5-dimethyl piperazine as a hydrogen chloride acceptor.
