摘要： A process for producing an aliphatic polyester through the ring-opening polymerization of a cyclic ester, wherein at least a late stage of the polymerization is caused to proceed as a solid-phase polymerization reaction and the aliphatic polyester yielded is subjected to a step for removing the residual cyclic ester to a gas phase. Thus, an aliphatic polyester can be obtained in which the content of the residual monomer has been minimized.

摘要： A process for producing a polyarylene sulfide which includes a dehydration step in which a mixture comprising an organic amide solvent, an alkali metal hydrosulfide, and an alkali metal hydroxide the amount of which is 0.95 to 1.05 mol per mol of the hydrosulfide is dehydrated by heating. According to need, an alkali metal hydroxide and water are added after the dehydration step so that the total number of moles of the alkali metal hydroxide becomes 1.00 to 1.09 per mol of the sulfur source including the alkali metal hydrosulfide present in the system and the number of moles of water becomes 0.5 to 2.0 per mol of the sulfur source introduced. A polymerization step is conducted through two stages.

摘要： A process in which an aliphatic polyester having improved water resistance is obtained using water positively as an initiator and/or molecular weight modifier. In the process, a cyclic ester containing as an initiator and/or molecular weight modifier a proton source compound containing water in an amount larger than 80 ppm is subjected to ring-opening polymerization using the total proton concentration in the cyclic ester as an index and a carboxy-blocking agent is incorporated into the resultant aliphatic polyester to thereby produce an aliphatic polyester.

摘要： Monofilaments comprising resin compositions which contain 1% by mass or more of a comonomer component (for example, hexafluoropropylene), have an intrinsic viscosity of 1.3 dl/g or more and a melting point of 165 DEG C or higher and contain a PVDF-based resin. Owing to the above composition and physical properties, the crystallinity and elastic modulus of the PVDF-based resin are altered. As a result, an appropriate flexibility can be imparted to the monofilaments while preventing deterioration in the mechanical properties.
