    摘要: A thermoplastic resin composition and a molded article having an antifouling property and exhibiting good antibacterial activity against Staphylococcus aureus and Escherichia coli are provided. A thermoplastic resin composition contains 5 to 95 parts by mass of a propylene resin (A), 5 to 95 parts by mass of at least one selected from the group consisting of an ethylene-based copolymer rubber (B) and a copolymer (B′) containing a monomer unit derived from an aromatic vinyl compound and a monomer unit derived from a conjugated diene compound, and a glycerol fatty acid ester (C), in which (C) is an ester of a fatty acid having 8 to 14 carbon atoms.

    摘要: This invention describes a polymer composition having reduced torque during processing comprising poly(ethylene terephthalate) (PET) and an internal additive, where the internal additive is a polyglycerol fatty acid ester having a degree of esterification of at least 70% and where the concentration of the internal additive is below 5 wt %. This invention further describes a use of said composition for packaging materials and a use of an internal additive in the processing of the polymer composition as a lubricant and/or an anti-blocker during processing of the polymer, where said internal additive is a polyglycerol fatty acid ester having a degree of esterification of at least 70% and 2-10 glycerol repeating units.

    摘要: A method for handling a sample of a biochemical substance with a biochemical tool is provided. The method comprises a step of bringing the sample of the biochemical substance into contact with the biochemical tool. The sample of a biochemical substance includes nucleic acids. The biochemical tool comprises a part configured to contact the sample of the biochemical substance, the part being made of a resin composition containing at least one cycloolefin polymer selected from the group consisting of a copolymer of a cycloolefin and a chain olefin, a ring-opened polymer of a cycloolefin, and a hydrogenated product of a ring-opened polymer of a cycloolefin, and an antioxidant, the resin composition comprising 0.01 parts by mass or more and 0.7 parts by mass or less of the antioxidant relative to 100 parts by mass of the cycloolefin polymer.
