There is provided a method of removing acids from the surface and interior of an acetate film produced by deterioration during storage. Such methods are characterized by extracting and removing the acids from the surface and interior of the acetate film, and the extraction treatment includes solvent extraction or evacuation (heating). This method suppresses the deterioration process in the storage of the acetate film.

Method of removing acid component in deteriorated acetate film

An ethylene-vinyl alcohol copolymer, represented by the formula (1):wherein n represents a number in the range of 15 to 15,000, and a method of producing an ethylene-vinyl alcohol copolymer wherein an 1,4 -polybutadiene is hydroborated in non-gel state in a solvent, followed by oxidation to be hydroxylated so as to derive an ethylene-vinyl alcohol copolymer represented by the formula (1):wherein n represents a number in the range of 15 to 15,000.

Ethylene-vinyl alcohol copolymer and process for producing the same

A resin composition to be used as a material for a various part of an automotive vehicle. The resin composition comprises a copolymer (A) formed by copolymerization of a first unsaturated monomer (a) and a second mononer (b). The first unsaturated monomer has a functional group which is bondable by hydrogen bond to a hydroxyl group. The second monomer is copolymerizable with the first unsaturated monomer. A metal oxide (B) is dispersed in the copolymer and having hydroxyl groups and hydrophobic groups at surface of the metal oxide.

Resin composition, thermoplastic resin laminate, and production methods thereof

A resin composition of the present invention comprises a polymer having functional groups and a metal oxide surface modified to form functional groups at a surface of the metal oxide and dispersed uniformly in the polymer. The functional groups of the polymer and the functional groups of the metal oxide are ionically bondable to the metal oxide and the polymer, respectively, so that the polymer and the metal oxide are bonded by ionic bonds to each other.
