Definitions
- the invention relates to a method for producing epoxidized polysulfides.
- Epoxidized polysulfides and processes for their preparation have long been known.
- a polysulfide containing thiol end groups and having very high molecular weights is first prepared from an organic dihalide and an inorganic polysulfide.
- sodium polysulfide For example, sodium polysulfide and
- the added alkali hydroxide serves as a catalyst.
- the destiUative purification of the polysulfide having epoxy end groups is carried out by means of thin-film distillation.
- a quaternary ammonium salt can also be added to the mixture as a phase transfer catalyst, then the desired amount of sodium hydroxide solution is preferably added continuously at normal pressure.
- the slightly viscous polymer is cleaned using a two-stage thin-film evaporator from Fischer, Meckenheim, with a total surface area of 0.45 m 2 at a pressure of 0.1-2 mbar.
- the yield based on the thioplast used is 98.5%; the product is obtained as a clear, light yellow, low-viscosity (2 Pas) liquid with a residual content of less than 100 ppm epichlorohydrin.
