In our work, zinc hexahydrophthalate (HHPA-Zn) was synthesized and its β-nucleating activity in isotactic polypropylene (iPP) was confirmed. The single crystals of HHPA-Zn were obtained for the first time, with the crystal structure analyzed. The results of differential scanning calorimeter (DSC) and wide-angle X-ray scattering (WAXS) showed that HHPA-Zn increased the crystallization temperature of iPP by 11.2 °C and induced considerable amount of β-crystalline iPP (β-iPP) with the K_β up to 0.66. The investigations of the mechanical performance of iPP showed an increase of 193% in the impact strength with the help of HHPA-Zn. Based on the crystal structure data and the lattice matching theory, the structural matching mechanism of HHPA-Zn and iPP was proposed, and the crystallization process of iPP induced by single crystals of HHPA-Zn was observed by polarized light microscope (PLM) to support the epitaxial crystallization of β-iPP. Flash differential scanning calorimeter (Flash DSC) was conducted to explain the formation of a bit α-crystalline in crystallization.

六氢邻苯二甲酸锌与全同立构聚丙烯β相的结构关系

在我们的工作中，合成了六氢邻苯二甲酸锌（HHPA-Zn），并证实了其在等规聚丙烯（iPP）中的β成核活性。首次获得HHPA-Zn单晶，并对其晶体结构进行了分析。差示扫描量热仪（DSC）和广角X射线散射（WAXS）的结果表明，HHPA-Zn使iPP的结晶温度提高了11.2°C，并诱导了相当数量的β-结晶iPP（β-iPP）。该ķ _β高达0.66。对iPP力学性能的研究表明，借助HHPA-Zn，冲击强度提高了193％。基于晶体结构数据和晶格匹配理论，提出了HHPA-Zn和iPP的结构匹配机理，并通过偏光显微镜（PLM）观察了HHPA-Zn单晶诱导的iPP的结晶过程。 β-iPP的外延结晶。进行了闪速差示扫描量热仪（Flash DSC），以解释结晶过程中α-晶状位的形成。
