Abstract
AbstractInitiation with a combined initiator n‐butyllithium/lithium tert‐butoxide in the ratio 1:6 brings the anionic polymerization of 2‐ethylhexylacrylate (EtHA) in toluene and n‐heptane at temperatures between −78 and −20°C up to a quantitative conversion. In the initial stages of the process the molecular weight distribution (MWD) of the products is polymodal as a result of the stablizing function of the alkoxide; MWD of the final product after a complete consumption of the monomer is medium, being visibly dependent on the reaction temperature and without any distinct content of low‐molecular weight components, which suggests a sufficient activity of all growth centers, and thus an essential restriction of side termination reactions.
