| Abstract: | Vinyl-type monomers containing bromine and/or phosphorus were synthesized and used as flame retardants for ethylene–propylene–diene terpolymer. The monomers were mixed with the base polymer, Sb2O3 as a synergist, radical initiator, and other additives, and polymerized in the matrix of the base polymer. The monomers act as an effective flame retardants when they form thermally stable polymers comparable to the base polymer. The efficiency was dependent on the amount of flame-retardant polymer formed in the finished compound. |
