摘要： A process for the manufacture of a partially cured polysulphide composition is provided, the curing of which is completed upon exposure of the composition to atmospheric moisture. The process comprises mixing a prepolymer with a water activatable curing agent and subjecting the composition to a partial cure with water. The reaction is then stopped by rapid dehydration after the initial induction stage of the reaction prior to the rapid increase in the viscosity of the composition. Curing of the composition is then completed by exposing the composition to atmospheric moisture.

摘要： In a process for producing a polyarylene thioether having high stability by dehalogenation/sulfurization reaction of an alkali metal (M) sulfide such as sodium sulfide and a dihaloaromatic compound such as paradichlorobenzene in a polar organic solvent, the haloaromatic compound is used excessively in an appropriate range rather than the alkali metal sulfide and the latter stage of the reaction or all period of the reaction is conducted under a powerful stirring condition to a certain degree to obtain the polyarylene thioether wherein the concentration of --SM or --SH groups of the polymer terminal is lowered. The polyarylene thioether thus obtained suppresses the coloration in the processing with an apparatus made of ferrous material such as extruder.
