摘要：
The crystalline structure of polybutene-1 (PB-1) with low tacticity was investigated by wide angle Xray diffraction and differential scanning calorimetry after heating to different melting temperatures and non-isothermal crystallization. The formation of form III was observed for the first time in the melt crystallization of PB-1 at atmospheric pressure. It was revealed that the fraction of the form III increased with the melting temperature during the non-isothermal crystallization. The results would be helpful to understand the crystallization and crystal transformation behaviors of PB-1. [GRAPHICS] .
