以纤维素碳酸苯酯为原料,合成了一种新型的含弱离子基团的两性聚硅氧烷。聚阴离子、聚阳离子和聚两性离子可通过正交去除保护基团而获得。通过FTIR和NMR光谱证明了分子结构。纤维素衍生物的特性,例如,用电位滴定法、比浊法、流变学和动态光散射法研究了酸离解常数、等电点和络合作用。初步研究了聚二甲基二烯丙基氯化铵与pH响应型插层复合物的形成。
A novel polyzwitterion possessing weak ionic groups could be efficiently synthesized from cellulose phenyl carbonate. Polyanion, polycation, and polyzwitterion are accessible by orthogonal removal of protecting groups. The molecular structure was proofed by FTIR- and NMR spectroscopy. Characteristic properties of the cellulose derivatives, e.g., acid dissociation constants, isoelectric point and complexation, were investigated by potentiometric titration (pH), nephelometry, rheology and dynamic light-scattering. The formation of pH-responsive interpolyelectrolyte complexes applying polydiallyldimethylammonium chloride was preliminary studied.
