Chain-like molecule是什么意思

用法例句

Effects of different long-chain molecules on properties of thermally-reversible transparent imaging materials;

长链分子对热可逆透明成像材料性能的影响

Compared with PBT/PET blend,the crystallinity of PBT/PCET blend is enhanced obviously,and the effect of ethylene glycol adipate is better,the crystalinity of PBT increases and that of PCET decreases with the increase in PBT content of copolyester in PBT/PCET blend.

本研究工作表明，以在ＰＥＴ分子链中引入少量柔性链分子如对苯二甲酸丁二醇酯、己二酸乙二醇酯等组成的共聚酯（ＰＣＥＴ）与ＰＢＴ共混，相对ＰＢＴ／ＰＥＴ共混体系，ＰＥＴ／ＰＣＥＴ共混体系的结晶度明显提高，即结晶更加完全，且以引入己二酸乙二醇酯效果更好；随共聚酯中ＰＢＴ含量增加，共混体系中ＰＢＴ结晶度一般升高，而ＰＣＥＴ结晶度降低；共混体系即使从熔体以３２０℃／ｍｉｎ快速冷却，其结晶也是完全的。
