There are provided: a bio-based coating composition which is a bio-based ingredient coating composition in consideration of environment and does not need any expensive ingredient and is also excellent in hydrolysis resistance; and an article coated with the coating composition. The bio-based coating composition is characterized by comprising the following film-forming ingredients: a lactic acid polymer (A) which contains a polyfunctional compound having a hydroxyl group and/or a carboxyl group in a functionality of not less than 3 and lactic acid as essential monomer ingredients and has a specific SP value; and a resin (B) which contains a hydroxyl group and/or a carboxyl group and has a specific SP value; wherein the difference (&#x394;SP) between the SP values of the lactic acid polymer (A) and the resin (B) is in the range of 0.2 to 4.0. The coated article is characterized by being obtained by being coated with the aforementioned coating composition.

Bio-based coating composition and its coated article

Provided is a method for producing a phenol condensate by oxidative condensation of a phenol compound not having a substituted group on at least one ortho-position, in the presence of a specific complex (II) and oxygen, wherein a condensate coupled at para-position of the phenol can be produced in an excellent yield,L-M (X)&#x2003;&#x2003;(II)wherein L represents a ligand having 2 to 4 nitrogen atoms as donor atoms, M represents copper ion, nickel ion, cobalt ion, iron ion, manganese ion, chromium ion or vanadyl ion, X represents a counter ion, n is a number of Xs.

Method for producing phenol condensate

It is to provide a method for producing hyaluronic acid or a hyaluronic acid derivative which is a simple preparation method as compared with a cockscomb extraction method or a fermentation method which has conventionally been employed industrially, and with which isolation and purification of the product from the reaction liquid is easy. It is a method for producing hyaluronic acid or a hyaluronic acid derivative, which comprises acting a hyaluronidase on an oxazoline derivative.

Process for producing hyaluronic acid or its derivative

There is disclosed a crystallizable poly(2,5-di-substituted-1,4-phenylene oxide), which exhibits an exothermic peak for crystallization of not less than 5 J/g at 150&#xb0; C. or over when cooled after melting, and/or an endothermic peak, at the time of melting of crystals thereof, of not less than 5 J/g at 150&#xb0; C. or over when re-heated after cooling of the melt, and which comprises a recurring unit of the following formula (I), and a method of preparing the same by polymerization of a 2,5-di-substituted-phenol of the following formula (II) by use of a copper complex catalyst made of a tridentate ligand of which nitrogen atoms coordinate to a copper atom in coexistence with oxygen:wherein R's independently represent a hydrocarbon group or a substituted hydrocarbon group, and they may be the same or different. The crystallizable poly(2,5-di-substituted-1,4-phenylene oxide) is able to provide a melt molding which has a reduced degree of coloration and good heat resistance.
