Reactive polymers, XXXVIII. Sorption of acid gases on macroporous 2,3‐epoxypropyl methacrylate copolymers modified by a reaction with amines

Abstract

Macroporous copolymers of 2,3-epoxypropyl methacrylate and ethylenedimethacrylate modified by aminolysis yielded sorbents with various contents of amino and hydroxy groups. The dependences of structural characteristics of these sorbents and of the sorption of sulphur dioxide on the content of crosslinking agent and on the cyclohexanol/dodecanol ratio used as the porogenic medium in the preparation of copolymers were investigated. The sorption of sulphur dioxide depends on the geometrical structure of the sorbent, concentration, chemical structure and accessibility of functional groups. ZUSAMMENFASSUNG:Eine Aminolyse von makropordsen Copolymeren aus Glycidylmethacrylat und Ethylendimethacrylat fiihrte zu Sorbentien mit einem unterschiedlichen Gehalt an Amino-und Hydroxygruppen. Es wurde die Abhtingigkeit zwischen strukturellen Parametern und der Schwefeldioxidsorption auf der einen und der Konzentration des Vernetzungsmittels und der porogenen Ldsungsmittel in der Polymerisationsmischung auf der anderen Seite untersucht. Die Schwefeldioxidsorption hangt von der geometrischen Struktur des Sorbens, der Konzentration, der chemischen Struktur und der Erreichbarkeit der funktionellen Gruppen ab.

Preparation of Polyglycidylmethacrylate Macropore Beads and Application in Candidaspecies 99–125 Lipase Immobilization

“…Glycidylmethacrylate (GMA) polymers contain reactive epoxide groups, which can react with sulfhydryl [13], amino [14,15], carboxyl [16,17] or hydroxyl groups [18]. This property is useful to form stable covalent bonds with biomolecules without any linkers or for introducing various functional groups.…”

Surface modification of cellulose filter paper by glycidyl methacrylate grafting for biomolecule immobilization: Influence of grafting parameters and urease immobilization

“…12 Epoxide groups directly react with sulfhydryl, amino and carboxyl groups to form stable covalent bonds with biomolecules. [13][14][15][16][17][18][19] Such epoxy-modified polymer surfaces are stable during long storage periods and resistant against hydrolysis. 20 Immobilization of biomolecules onto the matrix is generally carried out by means of entrapment, physical adsorption, copolymerization, or covalent attachment.…”

Preparation of monodisperse enantiomerically pure glycidyl methacrylate–ethylene glycol dimethacrylate copolymers in dispersion copolymerization: Functionalization

“…For decades, poly(glycidyl methacrylate)-co-(ethylene glycol dimethacrylate) (poly(GMA-co-EGDMA)), after derivatization by epoxide ring opening, have been used in a variety of analytical applications including chromatographic separation media [1][2][3], ion-resin exchange [4][5][6], supports for catalysis [7,8], solid phase reagent [9], solid phase synthesis [10], chromatography stationary phase [11], sorbents [12,13] and enzyme immobilization [14]. These materials are presented as spherical beads when produced by suspension polymerization.…”
