Claims
- 1. A resin composition which comprises:A. a thermoplastic resin, and, B-1. a fatty acid esters composition of a polyglycerine containing more than 70% of a fatty acid monoester represented by the general formula (1) described below: RCO—[OCH2CH(OH)CH2]n—OH (1) wherein R is an alkyl group, an alkenyl group, or a hydroxyl group-substituted alkyl group which has a carbon number ranging from 6 to 21, and n is an integer of at least 4, based on a peak area ratio detected using an ultraviolet ray absorption detector in a high performance liquid chromatographic analysis method; or B-2. a highly-purified fatty acid esters composition of a polyglycerine having an oxirane oxygen concentration of below 100 ppm, said oxirane concentration is defined by the titration method defined in Cd. 9-57 of Journal of American Oil Chemists' Society, or having a ratio of below 0.01%, said ratio is a peak area value of a chemical shift between 2.7 ppm and 2.8 ppm assigned by methylene proton derived from an oxirane group with respect to a peak area value of a chemical shift between 3.4 ppm and 4.4 ppm assigned by methylene proton and methine proton derived from a polyglycerine with a proton NMR.
- 2. A resin composition which comprises:A. a thermoplastic resin, and, B. a fatty acid esters composition of a polyglycerine containing more than 70% of a fatty acid monoester represented by the general formula (1) described below: RCO—[OCH2CH(OH)CH2]n—OH (1)wherein R is an alkyl group, an alkenyl group, or a hydroxyl group-substituted alkyl group which has a carbon number ranging from 6 to 21, and n is an integer of at least 4, based on a peak area ratio detected using an ultraviolet ray absorption detector in a high performance liquid chromatographic analysis method.
- 3. A resin composition which comprises:A. a thermoplastic resin, and, B. a highly-purified fatty acid esters composition of a polyglycerine having an oxirane oxygen concentration of below 100 ppm, said oxirane concentration is defined by the titration method defined in Cd. 9-57 of Journal of American Oil Chemists' Society, or having a ratio of below 0.01%, said ratio is a peak area value of a chemical shift between 2.7 ppm and 2.8 ppm assigned by methylene proton derived from an oxirane group with respect to a peak area value of a chemical shift between 3.4 ppm and 4.4 ppm assigned by methylene proton and methine proton derived from a polyglycerine with a proton NMR.
- 4. A resin composition as set forth in claim 1, wherein said thermoplastic resin is a polyvinyl chloride resin.
- 5. A resin composition as set forth in claim 1, wherein said thermoplastic resin is a styrene-based resin.
- 6. A resin composition as set forth in claim 5, wherein said styrene-based resin is at least one selected from the group consisting of a styrene homopolymer, a styrene-methylmethacrylate copolymer, a styrene-methylmethacrylate-acrylonitrile copolymer, a styrene-methylmethacrylate-methylacrylate copolymer, and a styrene-methylmethacrylate-methylacrylate-cyclohexylmaleimide copolymer.
- 7. A resin composition as set forth in claim 5, wherein said styrene-based resin is further mixed with a phosphorous compound and, optionally, a polyalkyleneglycol.
- 8. A resin composition as set forth in claim 1, wherein said thermoplastic resin is a methylmethacrylate-based resin.
- 9. A resin composition as set forth in claim 8, wherein said methylmethacrylate-based resin is further mixed with pentaerythritols or fatty acid esters thereof.
- 10. A resin composition as set forth in claim 1, wherein said thermoplastic resin is a polyacetal resin.
- 11. A resin composition as set forth in claim 10, wherein said polyacetal resin has a Melt Index of less than 2.
- 12. A resin composition as set forth in claim 10, wherein an article molded from said acetal resin has a contact angle of less than 50.
- 13. A resin composition as set forth in claim 10; wherein said fatty acid esters composition is mixed together with a hindered amine compound.
- 14. A resin composition as set forth in claim 10, wherein said fatty acid esters composition is mixed together with a hindered phenol-based compound, fibrous titanium oxide, and at least one selected from the group consisting of a compound having nitrogen, a hydroxide of alkaline metal or alkaline earth metal, and a metal salt of a carboxylic acid or an inorganic acid.
- 15. A resin composition as set forth in claim 10, wherein said resin composition is molded as a shutter for a disk or a magnetic tape cartridge.
- 16. A resin composition as set forth in claim 10, wherein said resin composition is molded as an ink jet nozzle.
