1. Then the synthesis of ladderlike polysiloxane liquid crystalline with different mesogenic units was introduced.

2. The ladderlike polysiloxane liquid crystalline was a novel functional material with many excellent and special properties, such as stability, transparency and film forming characteristic.

3. The principle of ladderlike dividing and its approach were described and all kinds of critical instances were discussed.

4. Research in microstructure-controllable ladderlike polymer is a forward inter- and multidisciplinary field of polymer science, supra- molecular chemistry and material science.

5. A novel ladderlike polysiloxane with a reactive side group was synthesized via stepwise coupling polymerization.

6. At last, the difficulties of research on ladderlike polysiloxane were mentioned, and its development prospect was looked forward.

7. At last, the difficulties of research on ladderlike polysiloxane are mentioned, and the development prospect is looked forward.

8. The data show that the polymer has ordered ladderlike molecular structure.

9. A novel kind of ladderlike polysilsesquioxane having side-chain with chloropropyl terminal group was prepared by "Stepwise Coupling Polymerization".

10. Research in microstructure-controllable ladderlike polymer is the advanced and interdisciplinary study for polymer science, supramolecular chemistry and material science.

11. In this paper, the main advances in the research of the ladderlike polysiloxane liquid crystals in recent years are reviewed.

12. To solve the problem of limitation caused by large-size product in rapid-prototyping field and the difficult of combining, a method of ladderlike dividing was given based on STL file format.
