Analytical evaluation of the performance of stabilization

The most striking result emerging from the data is that the highest stabilization efficacy was achieved with the ternary mixture HALS/thiosynergist/phenol for all investigated hindered amines. The results discussed above would suggest a strong antagonism between HALS and thiosynergist because of the absent active aminoxyl radicals.

In this paper, a laser light scattering method was used for the determination of mutual solubilities in the systems of methanol + cyclohexane, aniline + heptane, and phenol + hexane at moderate pressures. Liquid−liquid equilibria (LLE) were measured from the region of solid−liquid equilibria (SLE) to the upper critical solution temperature. Freezing points in these systems were determined
