A functionalized chiral bis(oxazoline) is used as a chiral monomer in polymerization reactions leading to homo- and copolymers of different morphology. Polymers with a high content of chiral monomer lead to enantioselectivities that are higher than those obtained with the soluble ligand, but the chiral ligand is not used in an optimal way. A hyperbranched polymer, obtained by using a hexavinyldendrimer as the cross-linker, leads to the same enantioselectivities with a more efficient use of the chiral ligand.
一种功能化手性双（恶唑啉）用作聚合反应中的手性单体，可生成不同形态的均聚物和共聚物。含有高含量手性单体的聚合物所产生的对映选择性高于使用可溶性配体时获得的对映选择性，但手性配体未得到最佳利用。通过使用六乙烯基树枝状大分子作为交联剂获得的超支化聚合物，在更有效地利用手性配体的情况下可产生相同的对映选择性。
