More precisely, the invention relates to a method for producing primary polycondensates, which comprises a step of polycondensing a dicarboxylic acid component having a terephthalic acid content of from 60 to 100 mol % and a diamine component in which the amount of 1,9-nonanediamine and/or 2-methyl-1,8-octanediamine falls between 60 and 100 mol %, in the presence of water of being from 15 to 35% by weight, at a reaction temperature falling between 250.degree. C. and 280.degree. C. and under a reaction pressure (P) that satisfies the following formula (1):P.sub.0 .gtoreq.P.gtoreq.0.7 P.sub.0 (1)where P.sub.0 indicates the saturated vapor pressure of water at the reaction temperature, to form a primary polycondensate, followed by a step of taking the resulting primary polycondensate as formed in the previous step out of the reactor in an atmospheric environment while it is at a temperature within the same range as in the previous step and has a water content within the same range as in the previous step. The invention further relates to a method of polymerizing the primary polycondensate prepared previously into a polyamide having an increased molecular weight.

摘要： A water purifier has a deodorization tank for removing ions and odorants by adsorption from running water and a mesh filter for removing dust. The mesh filter is arranged at a water entrance of the deodorization tank. The deodorization tank contains an anti-bacterial membrane having a function of imparting an antibacterial activity to the water by supplying mineral ions to the running water and thereby alkalifying the water. The deodorization tank also has a water exit which is associated with a mineral supply filter for supplying a mineral component to the running water. The mineral supply filter is prepared by molding a powder obtained by adhering a material such as soda glass to the surface of heat-decomposed calcium carbonate.

摘要： The present invention provides a polyamide resin composition not only having an appropriate melt viscosity despite addition of a conductive filler thereto but also having excellent moldability, conductivity, low-temperature impact resistance, and fuel barrier properties. The present invention is a polyamide resin composition containing specific amounts of a polyamide, a modified resin, and a conductive filler. The polyamide contains: dicarboxylic acid units containing 50 mol % or more of terephthalic acid units and/or naphthalenedicarboxylic acid units; and diamine units containing 60 mol % or more of aliphatic diamine units having 4 to 18 carbon atoms, and has terminal amino groups in an amount of 5 to 60 μmol/g. The modified resin has been modified with an unsaturated compound having a carboxyl group and/or an acid anhydride group. In the polyamide resin composition, a difference between the number of moles (MI) of the terminal amino groups of the polyamide and the number of moles (MII) of the carboxyl groups and the acid anhydride groups of the modified resin in 1 g in total of the polyamide and the modified resin is −5.0 μmol or more and less than 4.0 μmol, and the number of moles (MII) is more than 4.0 μmol.
