Popis:	1. The kinetics of the polymerization of p-chloro-, 2,4-dichloro- and 2,4,6-trichlorophenyl methacrylates are similar in character to those of the polymerization of methyl methacrylate: an initial linear reaction period is followed by a sudden acceleration of polymerization accompanied by an increase in molecular weight of the polymer. 2. The influence of the chlorine in the phenyl ring of the methacrylic ester is manifested in a lower degree of conversion and in an earlier termination of the period of self-acceleration with increasing chlorine content. 3. Replacement of the methyl group of methacrylic ester by the bulkier chlorophenyl group is reflected in a higher reaction rate and in stoppage of polymerization after a lower degree of conversion. 4. A theory of the causes of these phenomena is advanced on the basis of the experimental data.
