What is glass transition temperature (Tg)? What are the units of glass transition temperature? Which type of polymers undergo glass transition? What are the examples of polymers with high or low Tg? What is the difference between Tg and Tm? Why is it important to identify the Tg of polymers? What are the factors affecting Tg?

Linear low-density polyethylene (LLDPE) is a substantially linear polymer (polyethylene), with significant numbers of short branches, commonly made by copolymerization of ethylene with longer-chain olefins.

2011年4月1日 · LLDPE-g-MA has been found to be an effective compatibilizer in LLDPE/EMA system as it improves thermal stability of the systems by providing improvement in the interfacial interaction between LLDPE and EMA. The compatibilizer increased the decomposition temperature of these systems especially at a critical value of its concentration in the blends.

实验采用RJY-IP型静态热机械分析仪测试Tg，测试温度范围：室温到250 ℃，升温速率为 5/min。 实验讨论了不同CTBN、TiO2含量对改性的环氧树脂玻璃化转变温度的影响。不同CTBN含量时改性环氧树脂的TMA曲线和Tg值如图11和12所示。

2019年3月28日 · The use of numerical methods to fit TG and DSC curves simultaneously may well allow obtaining a more comprehensive set of properties since both mass and energy released are taking into account. As a case of study, we selected linear low-density polyethylene (LLDPE) to carry out the analysis.

线性低密度聚乙烯（lldpe）是乙烯与少量α-烯烃共聚形成在线性乙烯的主链上，带有非常短小的共聚单体支链的分子结构。 线性低密度聚乙烯为无毒、无味、无臭的乳白色颗粒，密度为0.918~0.935g/cm3。

2023年10月13日 · When you heat up a specific type of plastic that doesn’t have a clear shape, it turns into a sticky liquid or feels like rubber at a certain temperature. This specific temperature is called the Glass Transition Temperature, or Tg for short.
