Simple Determination of the Linear Viscoelastic Region of a Polymer Using a Rheometer
Materials such as polymers exhibit viscoelastic behavior which is directly related to molecular structure and formulation differences. To accurately evaluate the relationships between molecular structure and viscoelastic behavior requires that experiments, such as rheological measurements, be conducted in regions where the viscoelastic properties observed are independent of imposed stress or strain levels. That is, experiments must be conducted in the linear viscoelastic region.
DetailsThermal Analysis Application Brief Determination of Polymer Crystallinity by DSC
Differential scanning calorimetry (DSC) provides a rapid method for determining polymer crystallinity based on the heat required to melt the polymer.
DetailsDSC Step Annealing for Fingerprinting Molecular Structure in Poly(vinylidene fluoride)
DSC step annealing is used to study the fine molecular structure of poly(vinylidene fluoride) (PVDF) homopolymers and copolymers. The melting pattern, obtained after step annealing, is a characteristic “fingerprint” for small variations in structure. This “fingerprint” detects variations in the polymerization process, the molecular weight of the polymer, the fraction and the nature of the co-monomer.
