摘要： A monomer mixture comprising .alpha.-methylstyrene or 2-isopropenylnaphthalene, methyl methacrylate, and acrylonitrile is polymerized in the presence of a crosslinked polymer obtained by copolymerizing a monofunctional monomer such as .alpha.-methylstyrene with a small quantity of a polyfunctional monomer such as divinylbenzene to obtain a copolymer (C). A vinyl chloride resin composition formulated by blending the copolymer (C) thus obtained with a vinyl chloride resin and an impact strength modifier resin in a specific proportion possesses improved thermal deformation resistance and impact strength while retaining processability comparable to that of the vinyl chloride resin mixed with the impact strength modifier resin.

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.
