α/β复合成核剂对等规聚丙烯结晶形态的影响及非等温结晶动力学OA北大核心CSCDCSTPCD
Crystallization morphologies and non-isothermal crystallization kinetics of isotactic polypropylene modified by α/β compounded nucleating agents
采用偏光显微镜(POM)及示差扫描量热(DSC)法考察了3种α/β复合成核剂NA40/NABW、NA40/HHPA-Ba、NA40/PA-03对成核等规聚丙烯(iPP)的结晶形态及非等温结晶动力学的影响.对成核iPP结晶形态的研究结果表明:α/β复合成核剂的加入能够减小iPP的球晶尺寸.影响α/β复合成核剂成核iPP结晶形态的主要因素是△TCp(△TCp为成核iPP结晶峰值温度与iPP结晶峰值温度的差值),即复合体系中△TCp较大的成核剂在iPP…查看全部>>
Crystallization morphologies and non-isothermal crystallization kinetics of isotactic polypropylene (iPP) modified by three a/j3 compounded nucleating agents (Nas) were studied by means of polarized optical microscope (POM) and differential scanning calorimeter (DSC). The size of spherulites in nucleated iPP appeared much smaller than that in pure iPP. However, iPP nucleated by different ratios of a/￡S compounded Nas showed different crystallization morpholo…查看全部>>
