Notes:
A thorough survey of the past and current available literature shows that the diffusion of the solvents toluene, ethylbenzene, ortho-, meta-, and para-xylenes in polypropylene has not been studied so far, although such studies find practical applications in various industrial problems. Diffusitives and the activation energies of the above mentioned solvents in polypropylene were determined in the temperature range of 45-120°C by gas chromatography. The values obtained in this communication compare fairly with those determined by conventional techniques for analogous systems, confirming the reliability of the gas chromatography as a powerful tool for diffusion measurement and the authenticity of the data presented herein.
