Notes:
The anionic polymerization of butyl acrylate initiated with a system consisting of the P4-tert-butyl base and isobutyric acid methyl ester was investigated. The major fraction of the polymer contains a butoxy endgroup. The role of the non-coordinated butanolate in initiating the polymerization reaction, its probable formation, and consequences effecting the polymerization are discussed. NMR investigation reveals that 5% of the isobutyric acid methyl ester are deprotonated by the P4-tert-butyl base in the equilibrium state at -50°C whereas 11% of the acetic acid ethyl ester are deprotonated. The formation of block copolymers is observed on sequential addition of butyl acrylate and methyl methacrylate.
