Abstract
The article presents the results of (meth)acrylate polymerization in THF initiated with various complexes of methyl 2-lithioisobutyrate (MIB-Li) and lithium tert-buioxide (t-BuOLi), prepared from the components in mole ratios 1:3, 1:6 and 1:10 in THF and aged for various time periods and at various temperatures. In dependence on the component ratio, temperature and storage time, the mixtures form cubic cross-aggregates with MIB-Li/t-BuOLi mole ratios 3:1, 2:2 and 1:3 which exhibit different behavior when used as initiators. It was found that the way of synthesis of the complex and its structure not only affect the kinetics of polymerization but also distinctly change the microstructure of the formed polymers.
