PE and PP differ in the relative numbers of these CH bonds. Although 3 CH bonds are the most reactive the abundance of 2 and 1 CH bonds in PE and PP respectively increases the probability of reaction at these sites.
Until quite recently poly-α-olefin DRAs production used bulk polymerization of α-olefins such as 1-hexene 1-octene 1-decene and 1-dodecene in the presence of ZieglerNatta catalysts Hydrocarbon solutions of UHMW polyolefins have an extremely high viscosity the increase in viscosity during the reaction hampers α-olefin diffusion hinders heat transfer and provokes a chain termination.
1 dodecene molar mass. The mass transport hence becomes important and eliminating its resistance is required to reveal the reaction kinetics Visan et al 2014. As a result the mass transfer shall be taken into account to determine the intrinsic kinetics of CO oxidation over the PSF-supported catalysts the standalone tests were carried out in advance to evaluate the internal and external mass transfer resistance.

Melting point from molecular weight - Calculation of melting point of hydrocarbons from molecular weight molar mass Melting points of hydrocarbons alcohols and acids - Melting temperature C and F with varying carbon number up to C33. PE and PP differ in the relative numbers of these CH bonds. PEs comprise a majority of 2 CHs with smaller quantities of 1 and 3 CH bonds while the molar ratio of 1.
3 CH bonds in PP is 321. Although 3 CH bonds are the most reactive the abundance of 2 and 1 CH bonds in PE and PP respectively increases the probability of reaction at these sites. Where η is in units of µPa s and M is the molar mass in gmol.
Kinetic theory also gives a relation for the mean velocity v of molecules of mass m. Gas Air Ar CO2 H2 He Kr N2 NH3 Ne O2 Xe.
