专利号:WO-2024134480-A1 优先权日:2022-12-21 标题:Heterocyclic acrylic acid derivatives as monomers for the synthesis of polymers for use in ion exchange articles 发明人:RASMUSSEN JERALD K; HOCHSTEIN REBECCA A; FISHMAN JOSHUA M; VOLOSHIN ALEXEI M; WATTS ANNABELLE; RICHARDSON KRISTOPHER E; BISHOP LOGAN D C; GRIESGRABER GEORGE W; WLASCHIN KATIE F; COLAK ATAN SEMRA; JULIK EMILY; VAIL ANDREW W 权利人:3M INNOVATIVE PROPERTIES COMPANY 摘要:The present invention relates to monomers of formula (I) having a nitrogen atom that can be protonated at relatively low pH values (e.g., less than pH 9.5 or less than pH 9), polymers containing monomeric units derived from these monomers, anion exchange separation articles having the polymers grafted to a porous substrate, and methods of using the anion separation articles to separate mixtures of materials with different ionic content are described. Advantageously, the anion exchange separation articles can be used to separate biomaterials that cannot be subjected to high pH conditions (e.g., greater than 9 or 9.5) and/or to high ionic strength conditions (e.g., greater than 0.5M or 1M).
