Abstract
The persulfate‐initiated polymerization of allyl acetate has been studied at 70°C. in the absence and in the presence of sodium lauryl sulfate. In the absence of the detergent a polymer of molecular weight about 800 is formed from initially homogeneous reaction mixtures at an initial rate approximately proportional to concentration of persulfate and approximately independent of concentration of monomer. The ratio of the initial rates of disappearance of allyl acetate and persulfate is about 14, corresponding to the ratio calculated from the molecular weight. With a separate phase of monomer the molecular weight is about 1000. The addition of the detergent does not increase the rate of initiation or affect the molecular weight of the polymer formed in innitially homogeneous media, although the rate of polymerization is increased somewhat. With a separate phase of monomer the polymer formed in the presence of detergent has a molecular weight of about 1300.
