POLY(ESTERTHIOETHERAMINES), A NEW FAMILY OF TERTIARY AMINO POLYMERS

The aim of this letter is to report some preliminary results on the synthesis of a new family of tertiary amino polymers, poly(esterthioetheramines), as part of a wider research work on synthetic polymers containing the aminic function in the main chain. These new polymers can be obtained by stepwise polyaddition of bis( beta -mercaptoethylamines) to bisacrylic esters. The aminic comonomers, in turn, can be synthesized by ring opening addition reaction of bis secondary amines to ethylene sulfide. In this letter, the authors limited their investigation to bis( beta -mercaptoethylpiperazine) and a few selected bisacrylic estres. They gathered experimental evidence that both monomers and polymers synthesis can be considered as general, thus opening the way to a new family of macromolecular substances having potential interest both in the biomedical field, and as polymeric liquid crystals, as many tertiary amino polymers, and thioether polymers do. 14 Refs.
