To summarize, polymers are any material made up of molecular chains; plastics are synthetic, long-chain polymers that can be or have been shaped; and resins are solids or liquids that are subsequently（ [s?bsikw?ntli]adv. 随后） shaped into a plastic part. 因为树脂、塑料和聚合物之间密切联系,它们有时可以互换使用,尽管正确地使用有差别。总的来说,聚合物是指任何由高分子链结合而成的；塑料是合成的长链聚合物,可以或者已经成型,树脂是固体或液体,随后形成塑料部件。 2.The complexity in polymers arises because solid polymeric materials can exist, in two very distinct （ [disti?kt]独特的，有区别的） types of structure. In one type, the polymer molecules are randomly（ [r?nd?mli] 任意地）coiled （[k?ild]卷，盘绕） about each other with entanglemen .This structure type is called amorphous. In the second type, the polymer molecules can pack together into regular, repeating structu
