A resin composition includes a cellulose ester resin having a weight average molecular weight of 10,000 to 75,000; sulfuric acid; and at least one metal element selected from the group consisting of Group 1 elements and Group 2 elements, wherein a ratio of the sum of the content [M1] of the Group 1 element and the content [M2] of the Group 2 element to the total amount of all the elements according to fluorescent X-ray spectroscopy is 0.052% by weight, and a molar ratio of the content [M1] of the Group 1 element, the content [M2] of the Group 2 element, and the content [S] of sulfur atoms (S) according to fluorescent X-ray spectroscopy satisfies a relationship of Expression 1: ([M1]/2)+[M2]≧1.5×[S].

To provide a water-soluble film having excellent solubility, a packaging bag using the water-soluble film, a content release body using the water-soluble film, and a method for producing a water-soluble film. It is a water-soluble film prepared by film-forming a raw material containing a polyvinyl alcohol-based resin and a bisulfite. A bisulfite is added to the raw material containing the polyvinyl alcohol-based resin. Owing to this, the decrease in solubility of the water-soluble film is suppressed even though the raw material is maintained in a heating state for a predetermined time. This effect is the effect characteristic in a bisulfite, and is the effect that is not obtained in the case where a sulfite is used.

The objective of the present invention is to provide a thermoplastic resin powder that suppresses a decrease in fluidity of a composition during melt molding and that has a suppressed alteration of the resin resulting from retention. The thermoplastic resin powder is obtained by coagulating a polymer from a latex produced by means of emulsion polymerization of a monomer, the content of metal-corroding free acids in the thermoplastic resin powder is no greater than 500 ppm, and the thermoplastic resin powder satisfies a predetermined formula (1).

A flame-retardant composition endowed with intumescent properties which consists of an acrylic resin, a dehydrating compound, a blowing agent and, optionally, a fluorocarbon-based polymer.

A melt blended composition comprising, in weight percent (wt %) based upon the weight of the composition: (A) 55 to 94.99 wt % of a thermoplastic polymer, (B) 5 to 44.99 wt % of a moisture curable polymer, and (C) 0.01 to 5 wt % of a moisture condensation catalyst exhibits enhanced rheological and mechanical properties as compared to a composition alike in all aspects save for the presence of a moisture curable polymer.
