The change in linear size of the CPEMs as it swells was converted into a particle volume expansion ratio [[epsilon].
In addition, melt-blending polyethylene in a polystyrene matrix with the addition of a surfactant  followed by exposure to an electron beam to crosslink them can produce CPEMS of smaller size, and possibly free of surface terminal chains.
Squalane-swollen CPEMs with volume-averaged diameters of 16 [+ or -] 8 [micro]m were obtained from bulk XLPE by means of mechanical grinding both in cryogenic and in solvent-swollen state.
mix] = 0 as the chemical structure of the CPEMs and squalane are somewhat similar, and that the thermal expansion of the system is approximately equal to the thermal expansion of squalane due to the relatively low concentrations of CPEMs used.
The CPEMs were obtained using a method developed by White , whereby crosslinked polyethylene (XLPE) insulation layers were systematically stripped from recycled high-voltage distribution cable.
A TA Instruments DSC 2920 (TA Instruments, New Castle, Delaware) was used to study the thermal properties and crystallinity of CPEMs in squalane.
