In this paper

the radical polymerization of methyl methacrylate (MMA) initiated with benzoyl peroxide (BPO)

lauroyl peroxide (LPO)

t-butyl hydroperoxide (TBH)

t-butyl peroxybenzoate (TBPB) and the effect of amine on the radical polymerization rate were studied

respectively. It was found that the order of polymerization rate Rp was as follows: LPO > BPO > TBH > TBPB. In the presence of tertiary amine such as N

N-di-methyl-p-toluidine (DMT)

N-ethyl piperidine (NEP)

the amine promoted the polymerizatio of MMA

and the order of Rp changed to BPO-amine>LPO-amine>TBH-amine>TBPB-amine.
