Title
(DE) RADIKALISCHE ATOMTRANSFER-POLYMERISATION UNTER BIOLOGISCH VERTRÄGLICHEN BEDINGUNGEN
(EN) ATOM TRANSFER RADICAL POLYMERIZATION UNDER BIOLOGICALLY COMPATIBLE CONDITIONS
(FR) POLYMÉRISATION RADICALAIRE PAR TRANSFERT D'ATOMES DANS DES CONDITIONS COMPATIBLES DU POINT DE VUE BIOLOGIQUE
Abstract
(EN) Methods for conducting controlled grafting-from radical polymerizations from biomolecules under conditions that are biologically compatible are described. The methods provide biomolecule-polymer conjugates with highly controlled structures and narrow polydispersities under aqueous reaction conditions and biological temperatures. Biomolecules, such as proteins and nucleotides can be conjugated to polymers with high levels of control.
(FR) La présente invention concerne des procédés de mise en œuvre de polymérisations radicalaires sous une forme de greffage contrôlé à partir de molécules biologiques dans des conditions qui sont compatibles du point de vue biologique. Les procédés de l'invention mènent à des conjugués polymères-molécules biologiques ayant des structures hautement contrôlées et des polydispersités étroites dans des conditions aqueuses de réaction et des températures biologiques. Des molécules biologiques, telles que des protéines et des nucléotides, peuvent être conjuguées à des polymères avec des niveaux de contrôle élevés.
