Condensation

This video provides an animated explanation of the formation of the polyester terylene from a dicarboxylic acid (benzene-1,4-dicarboxylic acid) and diol (ethane-1,2-diol). The process is known as condensation polymerisation - forming water molecules together with polyester molecules. In an accompanying video I look at the formation of the polyamide called nylon-6,6.

This video provides an animated explanation of the formation of polyesters from dicarboxylic acids and diols. The process is known as condensation polymerisation - forming water molecules together with polyester molecules. In accompanying videos I look at the formation of terylene and at polyamides, including nylon.
