Abstract : Pink and White banded colour polymers have been prepared in methacrylic acid/ benzoyl peroxide/ methanol/
hydroquinone /N, N- dimethyl aniline system at 30º C in a test tube having 9 mm inner diameter. Polymerization front was
initiated by adding N, N- dimethyl aniline at the top of the solution containing homogenous mixture of methacrylic
acid/benzoyl peroxide/methanol/hydroquinone which moves downward with a uniform velocity. The number of bands and
front velocity increases with increasing the initial concentration of benzoyl peroxide. The measurement of the front
temperature by a thermocouple with respect to front position shows a slow increase in temperature followed by sharp
increase to a temperature up to 150º C and followed by slow decrease of few ºC. These colour band polymers appear in a
range of initial concentration of benzoyl peroxide, methanol, hydroquinone, N, N- dimethyl aniline.
Keywords - Frontal polymerization, Oscillation etc.
