摘要：

The application of microwave heating for the separation of stabilizers from polypropylene and polyethylene was studied. Additives examined were the antioxidants IRGANOX 1010 and IGRAFOS 168 and the light stabilizer CHIMASSORB 81. The polymer samples were kept in sealed vessels and irradiated in a laboratory microwave oven. Fairly quantitative (>90% of the expected content) extraction of the stabilizers from powered polymer was achieved within 3 to 6 minutes using 1, 1, 1 ‐trichloroethane or the 1:1 mixture of acetone and n‐heptane as the extracting solvent. © 1990 Hüthig & Wepf Verlag, Basel
