Polymer Inclusion Compounds by Polymerization of Monomers in β-Cyclodextrin Matrix in DMF Solution

On the Structure of Beta-Cyclodextrin Polymer Adducts

“…The stability of polymer adducts alone, higher when compared with that of low molecular ones [1][2][3][4], supports the coaxial position of the polymer chain in the adducts investigated. If one supposes that the beta-CD molecules exist as pendant additive groups along the PVDC chain, the stability of beta-CD-PVDC and beta-CD-P(VDC + AC) should not differ from the stability of low molecular compounds/ cyclodextrin adducts.…”

“…A comparison of the free volume of the inside of the beta-CD molecule with the volume of the polymer segment filling it is morą convenient. If the length of the canal of the beta-CD molecule is 7.60 A and its diameter, cal-o culated on the basis of data for ąlpha-CD and gamma-CD (5 and 7.5 A, respectively) [ 11], equals 6.25 A, we obtain an inside volume of 233 A 3 . The volume of the polymer ąegment -(Cflb-CClzjs-has been calculated to be aą much as 188 A s , assuming 16.27 A 3 for -CHagroups and 46.46 A 3 for -CCI2-ones [ 18].…”

“…Such a consideration is supported by the fact that in the cases of polystyrene, poly(methyl methacrylate) poly-(methyl acrylate), and polymethacrylonitrile adducts, there is much more free space in the canal (according to molecular models) to make the beta-CD glucose units mobile. These adducts are unstable and dissociate as easily as low molecular ones [2,3].…”

Cyclodextrin Polymers

“…monomer was reported [148]. Many studies were devoted to "inclusion polymerization method," which means polycondensation of diamines with dicarboxylic acid dichlorides or polymerization of vinyl monomers in the presence of -CyD [149,150]. A major drawback of this method consists in lowering the monomer reactivity by inclusion, polymerization taking place mainly in the free state of the monomer.…”

Polyrotaxanes and Polycatenanes: Recent Advances in Syntheses and Applications of Polymers Comprising of Interlocked Structures

“…Maciejewski s group reported a series of papers which described several attempts at the preparation of pseudopolyrotaxanes in the solid state [79][80][81][82][83]. For example, the radiation polymerization of the crystalline adduct of vinylidene chloride and b-cyclodextrin yielded a pseudopolyrotaxane, in which one cyclodextrin occupied 2.9 repeat units of vinylidene chloride [80].…”
