摘要
采用纳米CaCO3作为载体制备了负载型β－成核剂，该β－成核剂成核PP研究表明，负载型β－成核剂成核PP不仅β－成核能力和β—晶含量高于非负载制的传统β－成核剂，而且成核剂PP的拉伸模量和冲击强度也高于非负载型的传统β－成核剂，归结于纳米CaCO3和β－成核存在协同作用。
A highly efficiency novel supported β-nucleating agent for polypropylene was prepared by in- situ chemical reaction with nano-CaCO3 as support and pimelic acid. The investigation on nucleated PP indi- cated that both β-nucleation ability and the content of β-PP were higher than that of non-supported calcium pimelate （CallA） β-nucleating agent. The tensile modulus and impact strength of PP nucleated by supported β-nucleating agent were higher than that of PP nucleated by non-supported calcium pimelate （CallA） β-nucleating agent. It is attributed to the synergist interaction of nano-CaCO3 and β-nucleation.
