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

Abstract

Summary: The radical homo‐ and copolymerization of styrene (1) and diethyl fumarate (DEF, 2) in the presence of methylated β‐cyclodextrin (β‐CD) in water is described. It has been shown for the first time that homopolymerization of CD‐complexed DEF and its copolymerization with CD‐complexed styrene occur readily in aqueous solution. In the absence of CD, or in organic solvents, the homopolymerization of DEF is strongly retarded.image

Cyclodextrin in polymer chemistry: Kinetic studies on the free-radical polymerization of cyclodextrin-complexed styrene from homogeneous aqueous solution

“…Furthermore, the preparation and polymerization of equimolar cyclodextrin complexes of commercial standard monomers like styrene 1 and methyl methacrylate (MMA have been described. It was also shown that the precipitation polymerization of a cyclodextrin complex of a poorly water-soluble monomer like MMA can be described by kinetic equations similar to those for the classical polymerization in solution [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Kinetic Studies upon the Influence of Cyclodextrin on the Polymerization of Methacrylamides in Homogenous Aqueous Solution

“…The free-radical [5][6][7][8][9][10][11][12][13][14][15] and controlled 'living' [16] polymerizations of various CD-complexed vinyl derivatives and also some other types of monomers in water have recently been investigated. The synthesis of electrical conducting polymers from aqueous media via oxidative coupling have also been described, [17,18] and some kinetics of the homoand copolymerization of several kinds of CD-complexed monomers in aqueous medium have been studied.…”

Copolymerization of Fluorinated Monomers with Hydrophilic Monomers in Aqueous Solution in Presence of Cyclodextrin

“…[1,2] We have shown in the last decade that suitable monomers can easily be polymerized in water by a free radical mechanism after their encapsulation in methylated bcyclodextrin (RAMEB) without using any surfactants or cosolvents. [3][4][5][6][7][8][9][10][11][12][13][14] During the chain reaction, in many cases, the RAMEB molecules slip off stepwise while the waterinsoluble polymer chains precipitate.…”
