改性MC尼龙的α/γ球晶与力学性能的关系

Relationship between α/γ Spherulites and Mechanical Properties of Modified Monomer Cast Nylon

尼龙的球晶由于其晶胞内部相邻大分子间不同氢键组合 ,产生不同的球晶结构 ,不同球晶类型的形成 ,决定MC尼龙性能。用红外光谱和X 射线衍射研究的球晶结构 ,发现共聚醚嵌段MC尼龙中的α和γ球晶的含量 。

Combination of different hydrogen bonds among adjacent macromoleculars inside crystal lite of nylon spherulites creates various structures of spherulites which determine the properties of mononer cast nylon (MC nylon).X ray diffraction and infrared adsorption show that content of α and γ spherulites in copolyether block MC nylon,especially the ratio of α and γ is the key factor influencing the properties of copolyether modified MC nylon.
