| abstract |
HEAT-RESISTANT, AS WELL AS TOUGH POLYMERS ARE PROVIDED CONSISTING ESSENTIALLY OF RECURRING UNITS OF AT LEAST ONE OF THE FOLLOWING FORMULAE: (CH3-CO)2-N-AR<(-CO-N(-)-CO-R(-CH3)2-C(-)=N-) WHERE N AND C ARE JOINED, AND (CH3-CO)2-N-AR<(-CO-N=C(-)-R(-CH3)2- CO-N(-)-) WHERE N AND C ARE JOINED WHEREIN AR IS SELECTED FROM HOMOCYCLIC AND HETEROCYCLIC TRIVALENT AROMATIC RADICALS, THE THREE VALENCES OF WHICH ARE LINKED TO DIFFERENT CARBON ATOMS, TWO OF SAID VALENCIES BEING LINKED TO ADJACENT CARBON ATOMS, AND R IS A TETRAVALENT ORGANIC RADICAL CONTAINING AT LEAST TWO CARBON ATOMS. PRECURSORS AND PROCESS TO PRODUCE THESE POLYMERS ARE ALSO DESCRIBED. |
