Polyazo sequential free radical initiators |
| abstract |
POLYAZO COMPOUNDS HAVING AT LEAST ONE AZO FUNCTION DIFFERENT FROM THE OTHER AZO FUNCTION(S). EXAMPLES: 4-ETHOXYCARBONYLAZO-4-CYANOPENTYL 4-T-BUTYLAZO-4-CYANOVALERATE; 2,2'' - AZOBIS(2-(4-T-BUTYLAZO-4-CYANOVALEROYLOXY)-4-METHYLPENTANE). ORGANIC SYNTHESES REQUIRING FREE RADICAL GENERATION IN TWO STAGES ARE CARRIED OUT USING AS THE SOURCE OF SEQUENTIAL FREE RADICALS A POLYAZO COMPOUND, AS DEFINED, WHEREIN AT LEAST ONE AZO FUNCTION IS RUPTURED IN THE FIRST STAGES AND THE REMAINING AZO FUNCTION(S) ARE RUPTURED IN THE SECOND STAGE. EXAMPLE: STYRENE MONOMER AND 4-ETHOXYCARBONYLAZO-4CYANOPENTYL 4-T-BUTYLAZO-4-CYANOVALERATE WERE REACTED AT ABOUT 76*C. TO OBTAIN A POLYSTYRENE CONTAINING FUNCTIONAL AZO GROUPS. THE POLYSTYRENE POLYMERS WAS REACTED WITH METHYL METHACRYLATE MONOMER AT 130*C. TO OBTAIN A BLOCK COPOLYMER OF POLYSTYRENE AND POLY(METHYL METHACRYLATE). |
