Abstract: An object to be achieved by the invention is to provide a biodegradable low-charging fiber. The prevent inventors have found that when a specific amount of a specific phospholipid that is not known to have antistatic properties is added to a biodegradable polymer, and the resulting mixture is formed into a fiber having a smooth surface, low-charging properties are developed. The invention has thus been accomplished. The invention is a fiber having an average surface porosity of less than 3% and made of a biodegradable polymer that contains a specific amount of a specific phospholipid.
Abstract: A composition includes a diene rubber and a metal phosphate ester of the formula: M being a metal with an oxidation state of +3 or +4, and R1 and R2 are independently selected from any organic moiety including hydrogen, except R1 and R2 cannot both be hydrogen. In addition, a method of making a rubber composition includes combining a solvent and a phosphate ester and mixing these to foam a solution. A source of metal ions is then added to the solution. The metal in the source of metal ions is selected from the group consisting of metals with an oxidation state of +3 or +4. The product is then is combined with a diene rubber composition to form a useful article, such as the tread of a tire.
