浅谈高分子材料 专业班级:09 级机电四班 姓 名: 学 号:摘要高分子,即高分子化合物,是由千百万个原子彼此以共价链接起来的大分子,因此又称为高聚物或聚合物。髙分子的特点是分子量大,高达 104~106,并且分子量具有多分散性,其相对分子质量一般都在几万到几百万。通常把相对分子质量在一万以上的分子称为高子。高分子是用相对分子质量、聚合度(重复的结构单元数)或分子链的长度来描述的。高分子材料的性能不仅与聚合物的化学性质有关,而且还与诸如结晶的程度和分布,高分子链长的分布,添加剂(如填料,增强剂和增塑剂等)的性质和用量等许多因素有关。 Summary Polymer, which polymer is determined by millions of atoms covalently linked to each other macromolecules, so-called polymer or polymer. Gao molecule is characterized by large molecular weight up to 104 to 106, and the molecular weight polydispersity, the molecular weight generally in the tens of thousands to several million. Typically the molecular weight of molecules in a million or more as high child. Polymer with molecular weight, degree of polymerization (number of repeating structural units) or a molecular chain length to describe. The performance of polymer materials and polymer chemistry is not only related but also with the extent and distribution, such as crystallization, polymer chain length distribution, additives (such as fillers, enhancers, and plasticizers, etc.) the nature and amount of many factors. 关键词:塑料、纤维、增塑剂、聚合物 高分子,即高分子化合物,是由千百万个原子彼此以共价链接起来的大分子,因此又称为高聚物或聚合物。髙分子的特点是分子量大,高达 104~106,并且分子量具有多分散性,其相对分子质量一般都在几万到几百万。通常把相对分子质量在一万以上的分子称为高分子。高分子是用相对分子质量、聚合度(重复的结构单元数)或分子链的长度来描述的。高分子材料的性能不仅与聚合物的化学性质有关,而且还与诸如结晶的程度和分布,高分子链长的分布,添加剂(如填料,增强剂和增塑剂等)的性质和用量等许多因素有关。高...
