Abstract: Preparation methods of polymer shish-kebab structure have been reviewed. Melt extruding casting, melt spinning, and solution crystallization method have been introduced. Research progress in formation mechanism and crystallization model for shish-kebab has been discussed. It was observed that spherulites and shish-kebabs will be formed from the isotropic and oriented melt via fold and bundle nucleus, respectively. In the process of shish-kebab formation, shish crystals and kebab crystals will form simultaneously. Shish crystals consists of extended chain, and kebab crystals consist of folded chain. Finally, prospect for application of shish-kebab structure has been indicated.

Key words: shish-kebab, preparation, mechanism, research progress
