It is proposed that this major step can be ascribed to the random chain scission of PHB by intramolecular cis-elimination, where degradation products like crotonic acid, linear oligomers with a crotonate end group and dimers and trimers of crotonic acid were formed.
Selective crosslink scission degree of devulcanization = 1 - [v.sub.e2]/[v.sub.e1] = 1 - [[gamma].sub.2] [(1 -[s.sub.2.sup.1/2]).sup.2]/[[gamma].sub.1][(1 - [s.sub.1.sup.1/2]).sup.2] (1)
By increasing the potential upto 300 V the changes induced by the accelerated lead ions in PVC are chain scission, cross-linking, swelling.
However, the other material initially undergoes a rapid decrease in viscosity typical of chain scission followed by an increase in viscosity which has been attributed to a process of crosslinking promoted by the oxidation that caused the initial breakage of the polymer chains.

The results in Table 1 indicate that the susceptibility of the different polymers to scission are more dependent on polymer composition than on the UV wavelength used in the experiment.
Where are: [h.sub.LSH]--water enthalpy incoming the manifolds, kJ/kg; [q.sub.p]--heat density flux in the economizer scission, kW/[m.sup.2]; d--Internal diameter of tube, m.
One might refer to scission and radical discord as what Dallmayr terms "an antidote to co-optation." As such it reflects the institution of cleavage against the prevalence of accommodation.
An example of this type of mechanism is the understanding that a specific polymer coating degrades by chain scission. Detecting the change in the chemical composition through quantitative Fourier Transform Infra Red (FTIR) spectroscopy can monitor this chain scission.
"Needles are not ideal for patients as piercing the skin is often painful and there is always a risk of bruising." The 20-second technique, called micro- scission, uses a stream of gas to bombard the skin with tiny crystals of inert aluminium oxide.
Elizabeth Caldwell, a political reporter with Stephens Media Group's Arkansas News Bureau, will make the jump from news journalism to public relations work, joining Brenda Scission's public relations staff at the state's second-largest advertising, marketing and public relations agency.
