Resumo(s)
Right now you are probably sitting on a comfy cushion. This is most likely filled with polyurethane (PU) foam. PUs are very long molecules made up of many repeating units. If the repeating units are prepolymers - intermediate-mass building blocks - with more than two reactive end groups, a three-dimensional network will form - a rubber, or elastomer, which can behave elastically depending on the degree of network cross-linking.
