采用Tzero技术DSC和调制DSC对合成橡胶混合物中的聚丁二烯进行定量分析
|

Polybutadiene is an elastomer widely used in industry (tires, belts, hoses, gaskets or seals) because of its mechanical and thermal properties, especially at low temperatures. It is very often used in combination with other elastomers or chemical compounds, and in blends at various percentages. Polybutadiene is a diene polymer, made from a monomer containing two carbon-carbon double bonds, specifically butadiene, and is an amorphous material. Differential Scanning Calorimetry (DSC) is used to detect the glass transition temperature (1) as a change in heat capacity. In the case of a small amount of polybutadiene in the compound, traditional DSC may not have enough sensitivity to detect the glass transition temperature. Traditional limitations of DSC are overcome by the new Tzero™ technology (2) with its improvements in sensitivity, quality of baseline, resolution, and wider modulation conditions in modulated DSC experiments. |
