    • Amino acid-based poly(ester amide) (PEA) macromers (e.g., functional PEA macromers) and methods for preparing amino acid-based poly(ester amide) (PEA) macromers. The functional PEA macromers can comprise functional groups such as hydroxyl, amine, sulfonic acids, carboxyl, thiol and acryloyl at the two terminuses of the PEA macromers. The content of the terminal functional groups on the macromers can be precisely controlled by adjusting the molar ratio of reactive monomers. The resulting versatility of these new functional PEA macromers can be used to fabricate a wide range of PEAs and PEA hybrid derivatives with very different chemical, physical, mechanical, thermal and biological properties. The functional PEA macromers can also be polycondensed into forming block PEA polymers.
    • 基于氨基酸的聚(酯酰胺)(PEA)大分子单体(例如功能性PEA大分子单体)和制备基于氨基酸的聚(酯酰胺)(PEA)大分子单体的方法。 功能性PEA大分子单体可以在PEA大分子单体的两个末端包含官能团,例如羟基,胺,磺酸,羧基,硫醇和丙烯酰基。 大分子单体末端官能团的含量可以通过调整反应性单体的摩尔比来精确控制。 这些新的功能性PEA大分子单体的多功能性可用于制造具有非常不同化学,物理,机械,热和生物学特性的各种各样的PEAs和PEA杂化衍生物。 功能性PEA大分子单体也可以缩聚成成型块PEA聚合物。
