The C=C double bond in ethene is involved in the polymerisation reaction. It allows ethene molecules to join, so it is an example of an addition reaction>. Poly(ethene) is an addition polymer.
In addition, utilizing the unique structures of the C1 polymers, success was made in preparing C1 polymers with enhanced acidity and much higher melting points, up to 130°C, compared to their ...
Addition polymers are made from molecules containing C=C bonds. Polymers have different properties and uses but it is difficult to dispose of them. DNA, starch and proteins are biological polymers.
