Abstract:
The present invention is related to a fuel composition for colored flames and an appropriate combustion device for using such composition which provides a fuel composition for colored flames with improved inflammability, realization of colored flames and persistency by having alcohol of low ignition point as a fuel, by adding a compound having an ester structure and by adding a fire power enhancer including at least 3 higher hydrocarbon. Also, the present invention provides a combustion device wherein the fuel composition is injected in fog so as to enhance ignition power when rendering colored flames by injecting through an injection nozzle and igniting, the size of flames can be controlled by adjusting pressure, and color of the flames injected through each injection nozzle portion can be realized in different colors respectively by a control device.
Abstract:
Disclosed is a method of preparing terminally functionalized telechelic polymers using a cationic living polymer product or a terminal tert -chloride chain end of a carbocationic quasiliving polymer product, which comprises quenching the polymer product with an N-substituted pyrrole to thereby functionalize the N-substituted pyrrole at the terminal reactive polymer chain end(s). Also disclosed are the terminal functionalized polyisobuyl N-substituted pyrrole compounds where the polyisobutyl group is substituted at the 2 and 3 position of the N-substituted pyrrole.
