【摘要】 本文通过ＷＡＸＤ，ＤＳＣ方法讨论成核剂（Ｎｄ２Ｏ３）对ＰＡ１０１０的聚集态结构的影响。用ＥＳＲ研究辐照不同聚集态结构ＰＡ１０１０体系的俘陷自由基行为。结果表明：俘陷自由基—ＣＨ２ＣＯＮＨＣＨＣＨ２—主要存在于结晶表面，结晶的表面积越大，俘陷自由基—ＣＨ２ＣＯＮＨＣＨＣＨ２—的含量越高，在一定条件下，如升温，常温放置一段时间，转化为俘陷自由基—ＣＨ２Ｃ＝Ｏ的量也越大；俘陷自由基－ＣＨ２Ｃ＝Ｏ主要存在于非晶区。更多还原

【Abstract】 In order to enhance the fold surface of the lamellae in crystalline polyamide 1010,heterogeneous Nd 2O 3 nuclei were introduced into the polymer.The free radicals captured in the irradiated PA1010 with different lamella fold surface areas were studied with ESR.It has been shown,that the captured radicals CH 2CONH C· HCH 2 were concentrated mainly in the fold surface of the lamellae.The larger the surface area is,the higher the captured radical concentration is.Under certain circumstances,such as heating or standing at room temperature,the larger the surface area is,the higher conversion of CH 2CONH C· HCH 2 to CH 2 C· =O is.The trapped radicals mainly exist in the noncrystalline domains.更多还原
