✦ Synopsis

Polymerization of methacrylamide has been carried out in the presence of ultrasound and peroxomonosulphate for the first time. The rate of polymerization and the rate of disappearance of peroxomonosulphate were followed simultaneously. A first order dependence on monomer and half order dependence with respect to peroxomonosulphate were found towards rate of polymerization. However, a first-order dependence on peroxomonosulphate was noted with rate of peroxomonosulphate disappearance. A suitable reaction scheme is suggested to fit with the experimental results. The composite rate constants for the polymerization were evaluated and compared for acrylamide and methacrylamide polymerization in the presence of ultrasound.

Radical polymerizations of styrene in the presence of C 60 have been conducted at 90°C in benzene using benzoyl peroxide (BPO) as initiator. The behaviors of C 60 are investigated by monitoring BPO concentration, C 60 content, and polymerization time. It is found that C 60 acts like a radical absorb
