An electrolyzed water generator includes anode, cathode, and cation exchange membrane provided between anode and cathode so as to be in contact with at least one of anode and cathode. Gaps in which a flow of water occurs are present between cation exchange membrane and at least one of anode and cathode.

Electrolyzed water generator and electrolyzed water generation system

An electrolytic liquid generation device according to the present disclosure includes an electrolytic part and a housing in which the electrolytic part is disposed. The electrolytic part has a laminate including mutually adjacent electrodes and a conductive film interposed between the electrodes. The electrolytic part electrolyzes a liquid. The housing includes an electrode case having a recess with an opening to enable insertion of the electrolytic part through the opening and to contain the electrolytic part in the recess, and an electrode case lid to cover the opening of the electrode case. The electrolytic part is contained in the recess such that lamination direction Z of the laminate is substantially aligned with a direction in which the opening opens. This configuration provides an electrolytic liquid generation device that can be built with improved facility.

The present invention relates to a modified styrene-maleic acid copolymer obtained by reacting a carboxylic acid group in a styrene-maleic acid copolymer with a halogen and/or epoxy compound. The modified styrene-maleic acid copolymer is useful as a low profile additive for a thermosetting resin, a water-absorbing material, etc.

Modified styrene-maleic acid copolymer and use thereof

The present invention relates to a process for decomposing a polymer into a monomer or oligomer by hydrolysis with sub- or supercritical water. The process of the present invention is characterized in that at least a part of the polymer is a polymer comprising a constitutional unit derived from an organic acid in the molecular structure, and the polymer being contacted with sub- or supercritical water in the presence of a water-insoluble base.

Depolymerization process

The present invention provides a method for decomposing a plastic so as to recycle useful substances therefrom as raw materials for a similar plastic. In particular, the present invention provides a method for decomposing a plastic, comprising the step of treating a thermosetting resin comprising a polyester and its crosslinking moiety, with subcritical water of a temperature lower than the thermal decomposition temperature of the thermosetting resin. According to the present invention, the thermosetting resin can be decomposed into a polyhydric alcohol, a polybasic acid and a compound comprising an acid residue derived from the polyester and a residue derived from the crosslinking moiety, without causing a random decomposition of the thermosetting resin.

Method of decomposing plastic

An epoxy resin composition of the invention comprises: an epoxy resin; a hardening agent; and a phenol-modified polyphenylene oxide having a number average molecular weight of 1000 to 4000, which is prepared by carried out a redistribution reaction between a polyphenylene oxide and a phenol compound in the presence of a reaction initiator which can be decomposed to generate an alcohol, a prepreg and a metal-clad laminate of the invention contain the epoxy resin composition.
