    • Described herein is a pentaalkyldisiloxane containing polymeric surfactant prepared by the copolymerization of an alkoxypolyoxyalkylenyl acrylate and an acrylate containing a pentaalkyldisiloxane group. A method for preparing beaded polyethylene glycol-based resins in silicone oil in the presence of a polymeric surfactant containing a pentaalkyldisiloxane group is also described. The average bead size can be controlled by varying the stirring rate, the polymerization temperature, the amount of surfactant, the type of solvent, and the amount of solvent. The surfactant does not interfere with the polymerization and can be removed together with residual silicone oil by a simple washing procedure. The resins can be used, for example, as a support for solid phase organic synthesis, as a chromatographic resin, as a resin for solid phase MAS-NMR spectroscopy, and as a carrier for drug molecules, various reagents, or scavengers.
    • 本文描述了通过丙烯酸烷氧基聚氧亚烷基酯和包含五烷基二硅氧烷基团的丙烯酸酯的共聚制备的含五烷基二硅氧烷的聚合物表面活性剂。 还描述了在含有五烷基二硅氧烷基团的聚合物表面活性剂存在下在硅油中制备珠状聚乙二醇基树脂的方法。 可以通过改变搅拌速度,聚合温度,表面活性剂的量,溶剂的类型和溶剂的量来控制平均珠尺寸。 表面活性剂不干扰聚合反应,可以通过简单的洗涤程序与残留的硅油一起除去。 该树脂例如可以用作固相有机合成的载体,作为色谱树脂,作为用于固相MAS-NMR光谱学的树脂,以及作为药物分子,各种试剂或清除剂的载体。 p>
