  • Polymer - an overview

    2010-6-7 · Polymer chains tend to lend the property of plasticity to the material (and hence the common term for manufactured polymers is 'plastic') because the chains – or parts of those chains – can be rearranged readily from the usual random coils (Fig. 2.3) to extended chains under moderate forces (Fig. 2.4).It should be noted that this kind of rearrangement for chain extension 1 does in fact ...
