✦ Synopsis

Cluster anions of methyl acrylate (MA) and methyl methacrylate (MMA) clusters were produced by electron transfer from high-Rydberg atoms of krypton and the mass spectra of the cluster anions were measured. The intensity of (MA), was particularly enhanced in the size distribution of MA); with an increase in the stagnation pressure of a sample gas seeded in helium, while no significant intensity enhancement was observed in the case of MMA); These results were interpreted as the occurrence of intracluster anionic polymerization in the formation of (MA);
