Cyclodextrins in polymer chemistry: Influence of methylated β-cyclodextrin as host on the free radical copolymerization reactivity ratios of isobornyl acrylate and butyl acrylate as guest monomers in aqueous medium

Cyclodextrins in polymer synthesis: Steric retardation of the free-radical polymerization in aqueous medium of 4-vinylbenzaldehyde/methylated -cyclodextrin complex

“…[4][5][6][7] More recently, we focused our interest mainly on the changes of the copolymerization parameters and the kinetics of the CD-complexed monomers compared to the behavior of corresponding uncomplexed monomers. [8][9][10][11] Thus, we have intensively investigated a new polymerization method covering the complexation of various hydrophobic monomers like (meth)acrylic esters or amides and styrene with methylated b-CD and the polymerization behavior in water as reaction medium. In almost all examples studied before, water insoluble polymers were obtained in a high yield.…”

“…In almost all examples studied before, water insoluble polymers were obtained in a high yield. [8][9][10][11][12][13][14][15][16][17][18] It was demonstrated that, generally during the propagation steps, the CD-host slips off from the monomer and the resulting polymer precipitates. Because of the high water solubility of the methylated CDs this component remains in solution.…”

Towards Green Routes for Polymer Synthesis: Polymerization of Cyclodextrin Host‐Guest Complexed Diethyl Fumarate and Copolymerization with Complexed Styrene in Homogenous Aqueous Solution

“…[1,2] For these reasons our group is focused on the use of cyclodextrins in polymer chemistry, a field that has recently received a great deal of industrial attention. [3][4][5][6][7][8][9][10][11][12][13][14] Cyclodextrins (CD) are cyclic oligomers of amylose consisting of six, seven or eight glucose units (a-, b-, g-cyclodextrin, respectively). The cyclodextrin molecules resemble a hollow truncated cone, with primary hydroxy groups at the narrower end and secondary hydroxy groups at the broader end.…”

“…This methylated b-CD, which is also used in consumer products, is synthesized industrially on a large scale and is therefore readily available. [15] We have recently investigated the free-radical [3][4][5][6][7][8][9][10][11][12][13][14] and controlled-''living'' [16] polymerizations of various CDcomplexed vinyl derivatives and also some other types of monomers under surfactant-free conditions. For example, the synthesis of conducting polymers under oxidative conditions [11,17] from aqueous media was described.…”

Cyclodextrins in Polymer Modification: Diels–Alder Addition of Cyclopentadiene/Methylated‐β‐Cyclodextrin Complex on Unsaturated Polyester and Formation of a New Type of Polypseudorotaxane

“…For example, in our group, the radical polymerization in aqueous solution of some hydrophobic monomers that were solubilized by complexation with methylated-b-CD was investigated and it was shown that higher monomer conversions were obtained as compared with the radical polymerization of uncomplexed monomers. [4][5][6][7][8] This concept has been also applied, for example, to the free-radical copolymerization of a water-soluble monomer (sodium 4-(acrylamido)-phenyldiazosulfonate) [9] or N-isopropylacrylamide) [10] with styrene, in aqueous solution using CD as solubilizer. Recently, the cross-linking reaction in a homogeneous aqueous medium of a watersoluble unsaturated polyester by use of a styrene/methylated-b-CD complex was reported.…”
