摘要：研究了不同的取代芳基杂环磷酸金属盐类成核剂对等规聚丙烯(iPP)性能及其微观形态的影响。结果表明:取代芳基杂环磷酸的一价金属盐类成核剂如钠盐(NA 11)、锂盐(NA 03)和钾盐(NA 19)具有很好的成核效果。当添加0.2%的钠盐、锂盐或钾盐时,iPP的拉伸强度可提高10%左右,弯曲模量可提高30%左右,雾度可降低40%左右,热变形温度提高25°C左右。而取代芳基杂环磷酸的二价金属盐如钙盐(NA 20)、镁盐(NA 12)、锌盐(NA 30)和三价的铝盐(NA 13)则基本上没有成核效果。对iPP及成核iPP的微观形态研究表明:不同成核剂的加入都可以降低球晶的尺寸,但一价钠盐(NA 11)降低iPP球晶尺寸的效果更显著,且生成的球晶更加致密和均匀。
Effect of metal salts of substituted aromatic heterocyclic phosphate on the properties and morphology of isotactic polypropylene （iPP） were studied. The results show that the monovalent alkali metal salts of substituted aromatic heterocyclic phosphate, such as sodium salt （NA11）, lithium salt （NA03） and potassium salt （NA19）, have good nucleation ability, 0. 2% of monovalent alkali metal salts are added to iPP, the tensile strength and flexural modulus of PP can be increased by about 10% and 30%, respectively, the haze value can be decreased by 40% or so, and the heat distortion temperature can be increased by about 25 ℃. But bivalent and trivalent metal salts have little effect on the properties of iPP. Meanwhile the studies of the morphology of iPP and nucleated iPP show that the addition of nucleating agents can decrease the spherulite size of iPP remarkably, in which NA11 has the best effect on the spherulite size of iPP.
