FREMGANGSMAATE FOR AA REDUSERE MISFARVING AV EN PLASTFORMMASSE VED BEARBEIDINGSTEMPERATUREN

摘要

In synthetic moulding compositions, especially those based on olefin polymers, which contain phenolic stabilisers and metal ions as catalyst residues, the discoloration at the processing temperature is reduced when they contain triglycerol or ditrimethylolpropane as catalyst inactivators.
