Method of inhibiting free radical polymerization of styrene |
摘要 |
The method of inhibiting free radical polymerization of styrene includes adding multi-walled carbon nanotubes are added to the styrene monomer. The addition of the multi-walled carbon nanotubes at a concentration of 5% by weight is found to provide effective inhibition of the polymerization of the styrene. Greater decreases in the conversion rate of styrene to polystyrene are found through the addition of multi-walled carbon nanotubes functionalized with a carboxylic group (COOH). Still greater decreases in the conversion rate of styrene to polystyrene are found through the addition of multi-walled carbon nanotubes functionalized with octadecylamine (C18H39N). The multi-walled carbon nanotubes may also be functionalized with other functional groups, such as octadecanoate, polyethylene glycol or phenol. The functionalized multi-walled carbon nanotubes only require addition at a concentration of 1% by weight to be effective in polymerization inhibition. |

1. A method of inhibiting free radical polymerization of styrene, comprising the step of adding a quantity of functionalized multi-walled carbon nanotubes to styrene sufficient to inhibit polymerization thereof, wherein the multi-walled carbon nanotubes are functionalized with a functional group selected from the group consisting of octadecanoate, polyethylene glycol, and phenol. |
