Abstract
A process for removing plastics from microstructures is disclosed. The metallic microstructure is treated with a high-boiling fluid at a temperature above 140.degree. C. for 10 to 90 minutes and subsequently rinsed with water. Suitable fluids include oligomers of ethylene glycol, short-chain diols and dicarboxylic acid esters. Such fluids do not attack the metal and prevent the plastics which are being removed from swelling.
