Methacryloyl chloride was polymerized in a number of solvents, and the polyacid chloride was converted into the methyl ester. The yield and viscometric molecular weight are given for each sample, whereas the osmometric molecular weight is given for selected samples. The choice of solvent controls the degree of polymerization between the limits of 500 and 8,800. Polymer yields were about 20% and the degree of polymerization was 1500 when dioxane was used as a solvent, whereas the yield increased to 45% and the DP was very high when such solvents as cyclohexane and n ‐hexane were used. Polymerization in solvent mixtures gave intermediate molecular weight values. Infrared analysis showed the presence of anhydride.
