- c) The physical characteristics of a polymer depend not only on its molecular weight and shape, but also based on the structure of the molecular chains. Classify the differences between all the molecular chains.7. The polymer polystyrene can be drawn in its long form in the two ways shown below. Circle/highlight the repeating motif in this polymer.
