1. As soon as such heterogeneity enters into a polymer chain, information technology becomes a theoretical possibility. 2. Scientists predicted that solitons should be very mobile, but only along the polymer chains. 3. The forces between atoms on a polymer chain are about two orders of magnitude stronger than those between chains. 4. As the size and shape of a polymer chain are of considerable interest to the polymer scientist it is useful to know how these factors can be assessed. 5. A polymer chain in dilute solution can be pictured as a coil, continuously changing its shape under the action of random thermal motions. 6. Polymer chains occupy a volume in space, and the dimensions of any macromolecule are influenced by the bond angles and by interactions between the chain elements. 7. The expansion of a covalently bonded polymer chain will be restricted by the valence angles between each chain atom. 8. The parameter is the average mean square of the unperturbed dimension, which is a characteristic parameter for a given polymer chain. |
