Procedure: To a solution of 2-Sec. butylphenol (1.5 g, 0.01 mole) 0.2 ml of Et3N was added under stirring. S-methyl ester of N-methylcarbamothioic acid (1.05 g, 0.01 mole) in acetonitrile (10ml) was added dropwise over a period of 4 hrs, keeping reflux temperature. After 30 hr, acetonitrile was evaporated under vacuum. The residue was taken in dichloromethane (25 ml), washed with water and a 5% cold NaOH solution, followed by water and brine and dried over sodium sulphate. After removal of the solvent, the liquid residue obtained was further purified by distillation to give 2-Sec. butylphenyl N-methylcarbamate of the formula VI; IR: 3329 (N--H), 1730 (--COO), 1535, 1490 and 750 (aromatic); PMR (CdCl3, 90 MHz): 0.81 (3H, 1, primary methyl of side chain), 1.18 (3H, d, J=7 Hz, secondary/methyl of side chain), 1.58 (2H, m, methylene protons of side chain), 2.88 (4H, doublet overlapping a multiplet, NH--CH3 and benzylic proton), 4.97 (1H, br s, N H) and 6.95 to 7.25 (4H, m, aromatic). keeping reflux temperature acetonitrile was evaporated under vacuum washed with water dried over sodium sulphate After removal of the solvent the liquid residue obtained was further purified by distillation

Procedure: A glass ampoule having an inner volume of 20 ml was filled with 2.08 g of BPMC (purity 96.0% by weight), 8.0 g of refined styrene, and 0.1 g of benzoyl peroxide (purity 99.8% by weight), displaced with nitrogen gas, and then sealed by fusion. This ampoule was kept immersed in a constant oil bath at 100° C. for one hour. Then, the ampoule was taken out of the bath, cooled, and opened. The reaction product was dropped into 500 ml of methanol and allowed to precipitate therein. The white solid consequently formed was separated by filtration and dried under a vacuum. The product consequently obtained weighed 5.8 g. The active oxygen content of the product was found to be 1.20%. In the infrared absorption spectrum of this product, absorptions by carbonyl group were observed at 1725 and 1795 cm-1 and a characteristic absorption by benzene ring was observed below 1600 cm-1. The data indicate that the white solid was a copolymer formed of styrene structural units and peroxycarbonate structural units. The conditions of copolymerization and the analyses of the produced copolymer are shown in Table 4A and the data on the copolymer's stability of storage are shown in Table 7. sealed by fusion cooled to precipitate The white solid consequently formed was separated by filtration dried under a vacuum The product consequently obtained a characteristic absorption by benzene ring
