摘要： Polyetheretherketone (PEEK) may be prepared by polycondensation of a single monomer (4-fluoro-4′-(4-hydroxyphenoxy) benzophenone) in diphenylsulphone (DPS) solvent and in the presence of sodium carbonate and potassium carbonate. The process can be used to produce high quality, relatively light coloured polymers having a lower Tm than those produced using a standard PEEK process.

摘要： The addition of nanoparticulate silica to sealants which are applied to the exposed edges of fire resistant laminated glazings provides an improved seal. Preferably the silica is present as an Ormosil dispersed in a polymerisable organic medium. Methods for applying such a medium to the edges of a glazing and polymerising it in situ are also claimed. The seals can be used to replace known metal tapes. The use of transparent seals provides a seal having an improved appearance.
