Abstract: 1. THE POLYMERIC COMPOSITION RESULTING FROM THE POLYMERIZATION OF 100 PARTS BY WEIGHT OF (A) AT LEAST 70% BY WEIGHT OF AT LEAST ONE NITRILE MONOMER HAVING THE STRUCTURE

CH2=C(-R)-CN

WHEREIN R IS HYDROGEN, LOWER ALKYL GROUP HAVING FROM 1 TO 4 CARBON ATOMS, OR A HALOGEN, AND (B) UP TO 30% BY WEIGHT BASED ON THE COMBINED WEIGHTS OF (A) AND (B) OF AN ESTER HAVING THE STRUCTURE

CH2=C(-R1)-COO-R2

WHEREIN R1 IS HYDROGEN, AN ALKYL GROUP HAVING FROM 1 TO 4 CARBON ATOMS, OR A HALOGEN, AND R2 IS AN ALKYL GROUP HAVING FROM 1 TO 6 CARBON ATOMS, AN ALKYL GROUP, OR AN EPOXY ROUP HAVING FROM 2 TO 6 CARBON ATOMS IN THE PRESENCE OF FROM 1 TO 40 PARTS BY WEIGHT OF (C) A RUBBERY COPOLYMER OF A CONJUGATED DIENE MONOMER SELECTED FROM THE GROUP CONSISTING OF BUTADIENE AND ISOPRENE AND AT LEAST ONE ESTER HAVING THE STRUCTURE CH2=C(-R1)-COO-R2 WHEREIN R1 AND R2 HAVE THE FOREGOING DESIGNATIONS WHEREIN SAID RUBBERY COPOLYMER CONTAINS FROM 5 TO 25% BY WEIGHT OF POLYMERIZED CONJUGATED DIENE AND FROM 75 TO 95% BY WEIGHT OF POLYMERIZED ESTER.
