（The effect of ethylene content on the curing time of ethylene propylene rubber (tc10) and process vulcanization time (tc90) is large, with the increase of ethylene content, the tc10 and tc90 of the material are shortened gradually, the content of the third monomer also has a certain effect on the tc10 and tc90, when the material is close to the same content of ethylene or the same, Zi alesi monomer etɔ̃lia me nyawo le ʋɛe la, zi nenemae nusi wotsɔ wɔe ƒe TC10 kple TC90 nɔa kpuie; Zi alesi nuawo ƒe torque (ml) le sue wu la, zi nenemae monomer etɔ̃lia me nyawo le ʋɛe.
The minimum torque (ML) of the material is mainly affected by the ethylene content, the higher the ethylene content, the greater the ML of the material, the worse the mobility at the beginning of vulcanization, because the maximum torque (MH) can reflect the modulus of the rubber, it can be seen that with the increase of ethylene content, the modulus of the rubber also increases gradually, the third monomer content on the modulus of the material is positively Ne esɔ kple monomer etɔ̃lia ƒe akpa si wowɔna la, zi alesi nusi wotsɔ wɔe la sɔ gbɔe la, zi nenemae nusi wotsɔ wɔe ƒe modulus lolonae, zi nenemae nusi wotsɔ wɔe ƒe modulus lolonae, zi nenemae nusi wotsɔ wɔe ƒe modulus lolonae.

With the increase of ethylene content, the low temperature resistance of the material gradually deteriorates, the same or similar ethylene content, the lower the content of the third monomer, the better the low temperature resistance of the material, this is because the ethylene content of ethylene propylene rubber increases, the degree of its molecular regularity will be higher and higher, and the ability of the macromolecules to crystallize is also gradually rising [10].
