Moving wave front have been investigated in acrylic acid / benzoyl peroxide / N, N-dimethyl aniline system in a test tube at 30oC temperature. Dependence of front velocity on initial concentration of benzoyl peroxide, and effect of hydroquinone was determined. Consumption of acrylic acid and benzoyl peroxide have been found to decrease exponentially with respect to front position. The variation of reaction temperature with respect to front position at different initial concentration of benzoyl peroxide and different initial starting temperature have been investigated. It has been established that the reaction temperature increases and attains a maximum value by increasing both benzoyl peroxide and initial reaction temperature. The rate of polyacrylic acid chain propagation has been determined.
