play a crucial role for the chain growth and chemical conversion of polymers in many cases. Among the spatialeffects are H-bonds, van der Waals interactions, ionic forces, dipolar interactions, self-ordering effects and steric influences.
Through IR-spectroscopic studies we have recently found that
tacticity of a polymeric chain is a result of spatial interactions between the active growing chain end and the free monomer or a monomer–metal complex. Moreover, the preferred head-to-tail chain growth of vinyl monomers can be a result of such spatialeffects. The spatial arrangement of polymer chains in

quantitative amidation reactions with aliphatic primary amines under mild conditions [7]. In the underlying study, we focused on spatialeffects with respect to interactions between neighboring lactide rings. Based on these findings, polymer analogous reactions of poly(MLA) with different alcohols were
