The invention relates to a quaternized segmented copolymer and a molecule inner crosslinking method thereof at high solid content. By means of the charge repulsion protection function, high-productivity molecular chain polymer Janus nano particles are obtained under the reaction condition of high solid content. The synthesis process is simple, the productivity is high, the yield is increased, the consumption of a solvent is greatly reduced, and the quaternized segmented copolymer can be used for volume production. The molecular chain polymer Janus nano particles have the structures and properties of an amphipathic segmented copolymer and nano particles and have important significance in the fields of catalysis, emulsification, oil and water separation, biological drugs and the like. 本发明涉及种含可季铵化嵌段共聚物及其高固含量分子内交联的方法，发明通过电荷排斥保护作用，实现了在高固含量反应条件下获得高产率的单分子链聚合物Janus纳米颗粒。合成过程简单、产率高，既提高了产量，又大幅度降低了溶剂的消耗量，可用于大批量生产。本发明的单分子链聚合物Janus纳米颗粒兼备两亲性嵌段共聚物与纳米颗粒的结构和性质，在催化、乳化、油水分离、生物药物等领域中具有重要意义。
