The process for chemically modifying metal-free, organic material for improving one or more properties thereof such as water dispersibility, compatibility with other organics, or increased chemical reactivity, wherein the process includes providing material with from 1-6 sulfonylhalide groups or sulfonate ester groups or mixtures thereof, and contacting the material under sulfonamido forming conditions with one or more reactants containing one or more poly(oxyalkylene) moieties, each of the reactants having from 1 to 4 functional amine groups, and each of the poly(oxyalkylene) moieties being comprised of from about 4 to about 200 epoxide reactant residues at least about 50 mole percent of which residues contain 2-4 carbons.
化学改性无金属有机材料以改善其一种或多种特性(如水分散性、与其他有机物的相容性或更高的化学反应活性)的工艺,其中该工艺包括提供具有 1-6 个磺酰卤基团或磺酸酯基团或其混合物的材料、在磺酰胺形成条件下,将材料与含有一个或多个聚(氧烷基)分子的一个或多个反应物接触,每个反应物具有 1 至 4 个官能胺基团,每个聚(氧烷基)分子由约 4 至约 200 个环氧化物反应物残基组成,其中至少约 50 摩尔%的残基含有 2-4 个碳。
