✦ Synopsis

The polymerisation mechanism of 2,6-dimethyl-P-cyclodextrin (Me2-P-CD) complexes of phenyl methacrylate (1) and cyclohexyl methacrylate (2) is described. The polymerisation of the complexes l a and 2a was canied out in water with potassium peroxodisulfate/potassium hydrogensulfite as initiator. The unthreading of the Me2-P-CD during the polymerisation led to water-insoluble poly(pheny1 methacrylate) (1 b) and poly(cyclohexy1 methacrylate) (2 b). By comparison, analogously prepared polymers from uncomplexed monomers 1 and 2 in homogeneous organic solvent (THF) with AIBN as radical initiator showed significantly lower viscosities and were obtained in lower yields in both cases.
