大分子单体(macromer),是一种链末端带活性基团、分子量为5000—13000的齐聚物。1974年,由美国化学家Milkovich等人首次研制出,并提出了大分子单体的概念。近十年来,随着离子聚合特别是阴离子活性聚合的发展,大分子单体的合成和应用也取得了很大的进展,已成为高分子设计中的一种有力手段。 Macromer is an oligomer with active groups at the chain ends and a molecular weight of 5000-13000. Developed by American chemist Milkovich et al. In 1974, the concept of macromer was first proposed. In recent ten years, with the development of ionic polymerization, especially anionic living polymerization, the synthesis and application of macromonomers have also made great progress, which has become a powerful means in polymer design.
