Abstract: PROBLEM TO BE SOLVED: To recycle nylon 6 resin formed bodies by depolymerizing nylon 6 resin formed bodies comprising specific automobile resin parts and obtaining recovered ε-caprolactam of high purity efficiently on an industrial scale. SOLUTION: Nylon 6 formed bodies comprising automobile resin parts that are composed of nylon 6 in an amount of >=90 wt.%, preferably >=95 wt.% of the total organic compounds in the formed bodies are depolymerized to obtain ε-caprolactam with the result that the nylon 6 resin formed bodies are recycled. Underhood parts are extremely suited to such an automobile resin part, and concretely, it is a cylinder head cover, an engine mount, an engine cover, a cover-cover, an oil pan, an air cleaner or the like. The resin formed bodies are preferably crushed into pieces, whose average weight per piece after crushing is

Abstract: PROBLEM TO BE SOLVED: To obtain a resin composition having high frame-retardancy and causing little bleed-out of the flame-retardant and lowering of the deflection temperature under load caused by the flame-retardant by adding a phosphorus- containing phenolic resin in combination with a specific compound to a thermoplastic resin. SOLUTION: This composition is produced by compounding (A) 100 pts.wt. of a thermoplastic resin (preferably a polyester resin) with (B) 1-100 pts.wt. of a phosphorus-containing phenolic resin and (C) 1-100 pts.wt. of a cyanuric acid salt or an isocyanuric acid salt of a triazine compound (preferably melamine, benzoguanamine or acetoguanamine). The component B is preferably a phenolic resin composed of the unit of formula I or formula II (R and R are each H or a 1-5C alkyl; (x) and (y) are each mol% of each of the unit of formula I and formula II in the polymer and x+y is 100). The resin can be produced e.g. by adding a phosphoric acid ester monohalide to a phenolic resin and subjecting the mixture to dehydrohalogenation reaction. The composition is preferably further incorporated with a non-halogenic flame-retardant to improve the flame-retardancy.

Abstract: PURPOSE:To provide a new polyarylene sulfide sulfone polymer of excellent heat resistance. CONSTITUTION:A polyarylene sulfide sulfone of a melt viscosity of 0.20-0.60, obtained by reacting an aromatic dihalosulfone with a bisphenol fluorene, an alkali metal salt and a source of sulfur. An aromatic dihalosulfone is reacted with bisphenol fluorene in a molar ratio of 99/1-60/40 in the presence of an alkali metal hydroxide or an alkyl metal salt in an organic amide solvent and/or an organic sulfone solvent to form an oligomer containing halogen atoms at both ends. A least one source of sulfur selected from among an alkali metal sulfide, an alkali metal hydrosulfide and hydrogen sulfide is added to the reaction mixture and reacted with the oligomer at 175-235 deg.C for 1-20hr. Thus, a resin having a high glass transition temperature and excellent heat decomposition resistance can be obtained. This process is industrially advantageous in that a polymer having a high glass transition temperature which can be varied can be obtained.
