How to identify polymers

WebGel permeation chromatography (GPC) is a type of size exclusion chromatography (SEC). It is mainly used to measure the molecular weight of polymer compounds. The molecular weight distribution shows how much molecular weight contains in a sample, and it is widely used for quality control to know the difference in the properties of polymer ... WebBasic polymers can be described by recycling code such as code 1 for PETE, polyethylene terephthalate. In this lesson activity students will become knowledgeable in six types of polymers and their common uses. Students will identify polymers by performing density measurements of each polymer.
