GRAFT COPOLYMERS ARE PREPARED IN A TWO-STAGE PROCESS BY FIRST REACTING, FOR EXAMPLE, 1,2-POLYBUTADIENE OR AN ETHYLENE/PROPYLENE/ALKYLIDENE NORBORNENE TERPOLYMER WITH DINITROGEN TETROXIDE TO FORM A NITRATED BACKBONE POLYMER HAVING INCORPORATED THEREIN NITRO AND NITRITE FUNCTIONS WHICH SERVE, IN THE SECOND STAGE OF THE PROCESS, AS SITES FOR THE SUBSEQUENT GRAFT COPOLYMERIZATION OF AN ACRYLATE MONOMER. |
