This study is the series of photopolymerization on alkyl methacrylate(AMA) to continue further research. The objective of this work is to investigate the environmental fraternitive characteristics of photopolymerization kinetics on n-Buthyl methacrylate(BMA) and comparing the decomposition behavior to other AMA. The experiment was done in aqueous solution under the influence of photo-initiator concentration$(0.05{\sim}0.25mol/l)$, light intensity$(5000{\sim}9000{\mu}J/cm^{2})$ and monomer concentration$(2.0{\sim}6.0mol/l)$. n-BMA was polymerized to high conversion ratio using hydrogen $peroxide(H_{2}O_{2})$, and the kinetics model we have obtained is as follows. $R_{p}=K_{p}[S]^{0.24}[M]^{0.33}[L]^{153}exp^{(27.19/RT)}$ The differential method of thermogravimetric analysis(Friedman method) was used to obtain value of activation energy on decomposition reaction. The average value of it was 27.5Kcal/mol.
