【摘要】 高分子链的柔顺性是指高分子链通过单键内旋转改变其构象的能力，是表征高分子物理特征的重要参数。高分子链柔顺性可分为静态柔顺性和动态柔顺性；分子链的主链结构、取代基(极性、体积、对称性及分布)、交联、分子间作用力及分子链长度，以及温度和外力等对其柔顺性有较大的影响；而高分子链柔顺性直接影响高分子材料的性能。更多还原

【Abstract】 The flexibility of polymer chains refers to the ability of polymer chains to change their conformation through internal rotation,and is an important physical quantity in polymer physics.The flexibility of polymer chains can be categorized into static flexibility and dynamic flexibility.The flexibility of polymer chains was significantly influenced by factors including the main chain structure,substituents (polarity,size,symmetry,and distribution),crosslinking,intermolecular interactions,chain length,as well as external conditions such as temperature and external forces.The flexibility of polymer chains directly affects the properties of polymer materials.更多还原
