Abstract: The present invention relates to [1] a plasticizer for a halogen-based resin including a condensate obtainable by an esterification reaction between a furan dicarboxylic acid compound and an aliphatic alcohol having 4 to 22 carbon atoms, in which the aliphatic alcohol includes a saturated aliphatic alcohol and an unsaturated aliphatic alcohol, and a content of the unsaturated aliphatic alcohol in the aliphatic alcohol is not more than 25% by mass; and [2] a halogen-based resin composition including the aforementioned plasticizer. The plasticizer has a plasticization performance for a halogen-based resin at a level identical to or higher than that of a phthalate-based plasticizer, and exhibits excellent effects of improving compatibility, heat resistance and cold resistance.

Abstract: Provided is a rubber composition containing a high stratified or tabular clay mineral content, wherein the dispersion of the stratified or tabular clay minerals is improved, thus reducing air permeability and improving flex resistance. Also provided is a tire using the rubber composition. An example of the rubber composition is a rubber composition containing a rubber component (A), a stratified or tabular clay mineral (B), and a glycerin fatty acid ester composition (C).

Abstract: Provided is a method for producing a difluorocyclopropane compound under milder reaction conditions and with high selectivity and high yield. The method for producing a difluorocyclopropane compound of the present invention is characterized by using sodium bromodifluoroacetate as a difluorocyclopropanation agent. With the disclosed method, a difluorocyclopropane compound can be produced under milder reaction conditions and with a higher conversion rate and a higher yield compared to conventional art. Further, by-products can be reduced significantly, thus allowing waste to be greatly reduced. Accordingly, the production method of the present invention is easy to implement industrially (can be employed on an industrial scale) and is thus extremely practical and useful.
