Пластмассы. Определение характеристик плавления (температуры плавления или температурного интервала плавления) частично кристаллических полимеров
Название (англ.):
Plastics; Determination of melting behaviour (melting temperature or melting range) of semi-crystalline polymers
Описание (англ.):
Specifies three methods for evaluating the melting behaviour of semi-crystalline polymers: Method A: A capillary tube method, which is based on the changes in shape of the polymer. Thismethod is applicable to all polymers, even if there is no crystalline phase. Method B: A polarizing microscope method, which is based on changes in the optical properties in the polymer. Not suitable for polymers containing pigments, which could interfere with the birefringerence of the polymeric crystalline zone. Method C: Thermoanalytic methods, C1: Differential thermal analysis (DTA); C2: Differential scanning calorimetry (DSC). Both are applicable to all polymers containing a crystalline phase.
