- Abstract
- Migration of three additives, n-octadecan, n-dotriacontane, and butylated hydroxytoluene (BHT), from linear (LPE) and branched polyethylene (BPE) into several oil-simulating solvents is studied at 30 to 60C. Diffusion coefficients of the three migrants from BPE into n-octanol are about the same as those into ethanol. A literature survey on the migration of organotin compounds, particularly di-n-octyltin stabilizers, from poly(vinyl chloride) into foods and food-simulants is also given.
