Тезаурус:

1. (However, in highly oriented polymers, such moduli can be found and chain scission does occur.
2. Failure of the chain links is called scission and it can be caused not only by strain but also by chemical means.
3. In extensional flow, however, provided the strain rate exceeds the relaxation rate, that is, the rate at which a chain attempts to re-coil itself in order to increase its entropy, full extension of a chain can occur and it is even possible to cause chain scission, as evidenced by molecular weight studies made on solutions which have been subjected to high extensional flows.
4. Scission and sunder, steal and plunder.
5. After a reprecipitation step, the pellets are rinsed twice with 80% ethanol to wash trapped traces of reagents, vacuum-dried, and subjected to standard cleavage reaction by heating in either piperidine (strand scission at the level of guanine residues) or NaOH (strand scission at the level of adenine and guanine residues) (1, 5).
6. Now we know that such a deformation cannot take place in a polymer, for if it did some atoms would move relative to their topological nearest neighbours by far more than covalent forces would allow, dissociation would occur (chain scission) and the nature of the polymer would change.
