Otherwise, Ethylene Diamine and Epichlorohydrin was grafted onto the polymer in order to improve the hydrophilicity. The product Phe resin with long chain (PS-Ace-EDA-ECH-Phe) was excepted to react with biochemical molecules easily.

• 此外,通过引入乙二胺、环氧氯丙烷等亲水性手臂链制得手臂链苯丙氨酸树脂(PS-Ace-EDA-ECH-Phe),这些亲水性手臂链的引入有望降低聚苯乙烯树脂的强疏水性,更易于同蛋白等大分子物质发生作用。
