Definitions

  • the azo initiator used in this method is not critical, it being possible to use the well-known ones. Suitable examples are azobisisobutyronitrile, 2,2′-azobis- (2,4-dimethylvaleronitrile), dimethyl-2,2′-­azobisisobutyronitrile, 2,2′-azobis-(2-methylbutyro­nitrile), 1,1′-azobis-(cyclohexane-1-carbonitrile), 2,2′-azobis-(2-cyclopropylpropionitrile), 2,2′-azobis-­(4-methoxy-2,4-dimethylvaleronitrile), etc.
  • the necessary conditions for the suspension polymerisation vary with the particular polymerisable vinyl monomer/s, and azo initiator/s used and the amounts thereof.
  • the optimum polymerisation temperature is generally 30° to 130°C, preferably 60° to 100°C, and the polymerisation time is preferably about 1 to about 10 hours.
