Abstract: Disclosed is a resin composition containing a biodegradable resin (A), a polyolefin resin (B) and a dispersing agent (C). The resin composition has a sea-island structure wherein the biodegradable resin (A) is dispersed like islands in the polyolefin resin (B) as the sea component, and the biodegrada ble resin (A) has an average dispersed particle diameter of not less than 1 nm but not more than 1000 nm. This resin composition contains a biodegradabl e resin such as a polylactic acid which places only a little burden on the e nvironment, and enables to obtain a molded article having moisture-proofing properties and dimensional stability equal to or higher than those of conven tional polyolefin molded articles, while maintaining the productivity of the conventional polyolefin molded articles.

Abstract: Provided is a polyester with an excellent color tone, and improved molding stability and mechanical properties. This improvement is achieved by controlling the electrical conductivity of the diol composition, which is a raw material for the polyester, to be between 0.6 mS/m and 30 mS/m, and preferably by controlling the pH of the diol composition to be between 5 and 7.5, thereby reducing the heating weight loss ratio of the polyester.
