摘要
综述了聚丙烯 (PP)增韧改性与结晶形态变化的关系 ,不同的共混组分对PP结晶行为的影响不同 ,分别有细化分割、共结晶、原位成纤复合等作用。无机刚性粒子及有机 /无机纳米粒子主要起到异相成核作用 ,诱发对增韧有贡献的 β 晶的形成。讨论了不同
The relationship of the toughening modification of PP to the changes of crystallization was reviewed.Different composition had different effect on the crystallization of PP,such as separation,insertion,cocrystallization and in situ fiber forming reinforcement.As heterogeneous nucleating agent,inorganic materials induced the formation of β crystals that contributed a lot to impact strength.The effects of different β nucleating agent on the crystallization of PP were also studied.
