γ-Benzyl-N-carboxy-L-glutamate anhydride and γ-methyl-N-carboxy-D-glutamate anhydride were synthesized by the use of a new recrystallization technique. The polymerization of these monomers was carried aut in o-dichlorobenzene, nitrobenzene and tetrahydrofuran using water, triethylamine and sodium hydroxide as initiator. In the polymerization of γ-methyl-N-carboxy-D-glutamate anhydride, the molecular weight of the polymer formed did not become higher in proportion to the extent of polymerization forty per cent or more. The polymerization of γ-benzyl-N-carboxy-L-glutamate anhydride in o-dichlorobenzene which is nonsolvent for the polymer led to lower molecular weight of polymer on agitating than the polymerization on the steady state, but the polymerization in nitrobenzene which is a solvent for it led to lower molecular weight of the polymer on agitating than the polymerization on the steady state.
