Self-polymerization of butadiene
Thread Content
What specific impacts do various factors such as temperature, pressure, gas-phase oxygen content, free water and rust, as well as storage time, have on the autopolymerization of butadiene?
I don’t think pressure affects self-polymerization; the effect of temperature on self-polymerization increases in an exponential manner, at 27. 6 degrees is a turning point; above this temperature, the self-polymerization rate increases. Oxygen, water, and rust, when combined, form peroxide-type initiators that accelerate self-polymerization.
Oxygen, water, and rust are essential for the formation of butadiene peroxides. Water and rust are involved in the decomposition reaction of peroxides, facilitating the formation of peroxide radicals; therefore, water and rust can be regarded as catalysts for the decomposition of peroxides.
