Abstract

Abstract A POLYMER HAVING ABOUT 10-10,000 REPEATING MONOMERIC UNITS PER MOLECULE, SAID UNITS BEING SELECTED FROM THE GROUP CONSISTING OF -CO-CH2-N(-CO-C(-R)=CH2)-CH2-CO-NH-Z-NH-, -OOC-CH2-N(-CO-C(-R)=CH2)-CH2-COO-Z- AND -OOC-CH2-N(-CO-C(-R)=CH2)-CH2-CO-NH-Z- WHERE R IS HYDROGEN OR A LOWER ALKYL GROUP AND Z IS AN ALKYLENE GROUP HAVING ABOUT 2-12 CARBON ATOMS. THIS POLYMER IS PREPARED BY A PROCESS COMPRISING: (A) FORMING A MIXTURE OF MONOMERS CONSISTING ESSENTIALLY OF; (I) A MONOMERIC DIESTER HAVING THE FORMULA CH2=C(-R)-CO-N(-CH2-COO-R'')2 WHERE R IS H OR LOWER ALKYL AND R'' IS LOWER ALKYL; (II) A MONOMER SELECTED FROM THE GROUP OF MONOMERS HAVING THE FORMULA H2N-Z-HN2, H2N-Z-OH, AND HO-Z-OH WHERE Z IS A LOWER ALKYLENE GROUP HAVING ABOUT 2-12 CARBON ATOMS; (B)HEATING THE MIXTURE OF MONOMERS AT ABOUT 50150*C. TO FORM THE POLYMER AND AN ALKANOL BYPRODUCT WHILE REMOVING SAID ALKANOL AS IT IS FORMED; AND (C) RECOVERING THE POLYMER.
