| Abstract | ||
| Calculation of heat content and entropy have been done for polyethylene for different chain length, are reviewed with support of data obtained from the thermo-chemical and thermodynamic for monomer unit and polyethylene, by using equations expressing these proportions at 25oC as a function of n, which is the number of ethylene units per polymer molecule, for gaseous state of monomer unit of ethylene to a narrow chain of polyethylene . We have reviewed for n the number monomer units per polymer molecule for n≥2, n≥4 and for (mono-olefin) n≥3, and at large numbers of n. | ||
