Thermal analysis is a well established characterization technique which measures physical properties, different types of phase transitions, the presence of volatiles and fillers, and compositional analysis. The other physical analysis techniques listed below can be useful in determining crystallinity, particle size and distribution, purity, and viscosity of your polymer sample, to name a few.
TGA is a thermal analysis technique that can provide characterization information that complements other analyses.
Compositional analysis for multicomponent polymers
DSC is a technique used to investigate the polymers response to heating.
Heat capacity (Cp)
Glass transition temperature (Tg)
Crystallization Temperature (Tc)
Melting Temperature (Tm)
This technique is used to detect crystalline phases, average crystallite size, and ratio of crystalline to amorphous phases in polymer materials. It is also a useful tool to determine the change in crystallinity of a polymer exposed to various environmental stresses or changes in crystallinity over time.
GC is a type of chromatography used for separating and analyzing small molecules that can be vaporized. This can be a useful for testing the purity of your polymer species.
Residual monomer content
Identifying different components of a mixture
Residual solvent content
DSV is used to measure a polymer’s intrinsic viscosity which is a measure of the change in solvent viscosity by the presence of polymer solutes in specific solvents and temperatures.
Based on the measured intrinsic viscosity of a polymer, the viscosity average molecular weight and hydrodynamic radius of polymers can be also be calculated.
DLS is a technique commonly used to detect the size and distribution of polymers that form a suspension in solution.
