Provided is a compound that can be used for a resin for a resist having excellent sensitivity, resolution, and etching resistance, or the like, by a compound represented by the following formula (1): (wherein Rrepresents a hydrogen atom or a methyl group, Rrepresents an aliphatic hydrocarbon group having 1 to 6 carbon atoms, m represents an integer of 0 to 5, and n represents an integer of 0 to 4).

Bifunctional (meth)acrylate compound and polymer

Provided is a method for producing a polymer for an electronic material having a low content of metal ion impurities and a polymer for an electronic material obtained by such method. The method for producing a polymer for an electronic material according to the present invention comprises a polymerization step of obtaining a polymer by polymerizing a monomer(s) and a purification step of adding a strong acid having 0 or less pKa to the polymer solution and subsequently performing an ion exchange treatment to reduce the concentration of the metal ion impurities.

To provide a novel ABA-type triblock copolymer of vinyl ether series, comprising polyvinyl ether and an oxystyrene-series unit, and a process of producing the ABA-type copolymer at a series of steps. The invention relates to a novel ABA-type triblock copolymer comprising Segment A comprising an oxystyrene-series repeat unit (a) and Segment B comprising a vinyl ether-series repeat unit (b), in which the Segment A and the Segment B are bonded together with a single bond, and to a simple process of producing the same. The triblock copolymer can be produced at a series of steps in a simple manner, comprising living cationic polymerization of a vinyl ether-series monomer such as ethyl vinyl ether in the presence of a bifunctional initiator and a Lewis acid, and subsequently adding an oxystyrene-series monomer such as p-hydroxystyrene for living cationic polymerization.

A method for carrying out a reaction of one substance capable of being activated by a catalyst with another substance capable of reacting with said one substance activated, characterized in that the substance capable of being activated is activated by passing the substance through a diaphragm type catalyst and the reaction is thus performed in one reaction step; a method for producing an aromatic alcohol utilizing the above method; and a reaction apparatus suitable for these reactions. In the method, one substance is activated by passing through a diaphragm type catalyst and an objective reaction is carried out by using the activated substance, and the reaction can be performed in one reaction step and with safety. Moreover, the contact of the above activated substance with a compound to be reacted therewith can be freely controlled, and therefore, over-reaction can be prevented and an objective product can be produced in high yield. The method is thus markedly advantageous from an economical view point as a commercial process for producing oxygen-containing organic compounds such as an aromatic alcohol, a ketone, an aldehyde, a carboxylic acid and an epoxide.

The present invention provides a process for producing 2-butanone and 2-butanol under comparatively mild conditions with a decreased number of steps by direct oxidization of a hydrocarbon, which is cheaper than butenes, as a raw material using molecular oxygen such as air. The process for producing 2-butanone and 2-butanol comprises directly oxidizing n-butane using molecular oxygen in the presence of aluminum phosphate containing transition metal atoms and a selectivity-improving agent, as required.
