What: "Macromolecules are like trains, molecules linked to molecules, in chains or in more complex structures. Sometimes all the wagons in a train are the same. We get additional polymers this way: a whole series of identical molecules hooked together like beads in a rosary thread. Polystyrene-the stuff of which disposable cups and packing cushions are made-consists of such identical molecules."
