Aiming at developing efficient interfacial agents for fiber‐reinforced composite materials, macromolecules are designed to have different components able to stick to the fiber and be compatible with the polymer matrix, respectively. Herein, macromolecules are prepared by solid‐phase synthesis considering phenylalanine residues to promote adsorption of the macromolecule on aramid fibers and aliphatic building blocks to interact with a hydrophobic polymer matrix. Using phenylalanine as building block for the preparation of macromolecules by iterative synthesis has been shown to be challenging. Thus, the screening of various parameters for the optimization of the synthesis of these macromolecules is discussed in this communication. A preliminary thermal study by thermal gravimetric analysis is conducted to evaluate their thermal stability.

含有苯丙氨酸和脂肪族结构单元的大分子的合成

为了开发用于纤维增强复合材料的有效界面剂，大分子被设计为具有能够粘附到纤维上并分别与聚合物基体兼容的不同组分。在这里，大分子是通过固相合成制备的，考虑到苯丙氨酸残基会促进大分子在芳族聚酰胺纤维和脂肪族结构单元上的吸附，从而与疏水性聚合物基质相互作用。使用苯丙氨酸作为通过迭代合成制备大分子的基础材料已显示出挑战性。因此，在本通讯中讨论了用于优化这些大分子合成的各种参数的筛选。通过热重量分析进行初步热研究，以评估其热稳定性。
