Background
The most important attribute of a polymer material is its basic chemical structure. Polyolefins, polyesters, polyurethanes, and polyamides are some examples of polymer materials. The composition of the polymer determines basic inherent properties that can be expected, such as chemical compatibility, softening temperature, melting temperature, and mechanical properties, for example.
Next in importance is molecular weight and molecular weight distribution. There are methods of analysis that reveal an average molecular weight. Melt flow rate, melt flow index, membrane osmometry, end-group analysis, and…
