segmented copolymer

[ Objective] The material consisting of poly ( ethylene glycol) and poly ( butylene terephthalate) segmented copolymer ( PEG/ PBT) has excellent mechanical properties and biodegradation characteristics.

[目的]聚乙二醇／聚对苯二甲酸丁二醇酯（PEG／PBT）嵌段共聚物具有良好的机械性能和生物可降解性，具备作为组织工程支架材料的基本特征。

The results showed that curve of tg δ ￣ T of PPO PHS PDMS is a high platform at range of-100 ￣ 125 ℃. It was found that segmented ternary copolymer is a very good the vibration damping properties material.

结果表明，该共聚物其tgδ随温度变化的曲线在－100～215℃范围内是一个很高的平台，说明它是一种优良的阻尼功能性高分子材料。
