摘要
大孔交联酰胺类聚合物是一类同时能提供氢键的给体(—NH—)和氢键的受体(—C O)的功能高分子材料。将D392乙酰化制得大孔交联聚(N-对乙烯基苄基乙酰胺)(PS-CH2NHCOCH3),并对其化学结构进行表征;测定了它在非水体系中对苯酚的吸附等温线,计算出不同吸附量时对应的吸附焓。结果表明,合成的大孔交联PS-CH2NHCOCH3在环己烷中对苯酚的吸附量大,吸附选择性高,排除了吸附过程的疏水作用及范德华力的影响因素,证明其吸附机理为氢键吸附。
Macroporous crosslinked amide resin, which contains both hydrogen acceptor and hydrogen donator, is a kind of functional polymer. Macroporous crosslinked poly （p-vinylbenzylamide） resin was synthesized by acetylation of D392 and characterized by element analysis and FT-IR. The adsorption isotherm lines of phenol onto the resin from non-aqueous system were measured, and the differential adsorptive heats for varied adsorption capacities （ AHm ） were calculated. The results indicated that the adsorption mechanism of phenol onto the resin from cyclohexane is based on hydrogen bonding.
