Abstract: PURPOSE:To produce a block copolymer of improved heat resistance by forming a polyphenylene sulfide-containing reaction solution in the first step and performing the formation and bonding of a phenylene sulfide ketone part in the second step by using the reaction solution. CONSTITUTION:An aprotic polar organic solvent (e.g., N-methyl-2-pyrrolidone) containing a dihalobenzene (e.g., p-dichlorobenzene) and an alkali metal sulfide (e.g., sodium sulfide) is heated to form a reaction solution containing a polyphenylene sulfide (step 1). A dihaloaromatic ketone (e.g., 4,4'- dichlorobenzophenone) is added to this reaction solution, and the obtained mixture is heated in the presence of an alkali metal sulfide and an aprotic polar organic solvent to form a block copolymer (step 2). Thus, a block copolymer comprising a polyphenylene sulfide part and a polyphenylene sulfide ketone part can be obtained, and this copolymer is excellent in heat resistance.

Abstract: PURPOSE:To selectively separate the objective substance by subjecting an isomer mixture of halogenated benzene derivatives to distillation or diffusion treatment, removing hydrogen halides, water and low-boiling components contained in the above-mentioned mixture and bringing the resultant mixture into contact with a zeolite adsorbent. CONSTITUTION:An isomer mixture of halogenated benzene derivatives (e.g., dichlorobenzene or chlorotoluene) is subjected to diffusion treatment for blowing an inert gas and removing volatile components or distillation treatment by a conventional method to remove hydrogen halides, trace amounts of water and low-boiling components formed as a by-product and the resultant mixture is then brought into contact with a zeolite adsorbent (e.g. ZSM-5) to afford the objective isomer. Since deterioration of the zeolite adsorbent can be prevented by previously removing the hydrogen halides, water and low-boiling components formed as the by-product, the objective isomer can be separated for a long period even without deteriorating productivity.
