Abstract:
VDF-based or TFE-based fluoroelastomers cured with peroxides in the presence of a co-curing agent and having terminal position iodine atoms derived by free-radical polymerization in the presence of iodinated triazine derivative of formula: whereinCYâ€²2, CXâ€²2, Xâ€²2C and Yâ€²2C represent carbon atoms bound to two Yâ€² or Xâ€² substituents, wherein Yâ€² is H, Cl, F, CH3, or CF3, and Xâ€² is H, Cl, F, alkyl or perfluoroalkyl C1-C3; mâ€² and tâ€² are 0 or 1, and mâ€² plus tâ€² is 0 or 1; pâ€² is 0 or 1, and is equal to 1 when tâ€² is 1; and nâ€² is an integer in the range of 2-20, in the presence of a free radical initiator.
