DETAILED DESCRIPTION We claim: 1. A thermoplastic resin composition which comprises (A) 10 to 90% by weight of a polyphenylene ether, (B) 90 to 10% by weight of a saturated polyester, and (C) 0. 1 to 10 parts by weight of an organic phosphorous acid compound represented by the formula: ##STR14## wherein n represents 1 or 2; Ar represents an aryl group having 6 to 30 carbon atoms or a substituted aryl group and when n is 2, Ars may be the same or different; and R represents an alkylene group having 2 to 18 carbon atoms or arylene group when n is 1 and represents an alkanetetrayl group having 4 to 18 carbon atoms when n is 2, based on 100 parts by weight of Components (A) and (B). 2. The composition according to claim 1, wherein said composition comprises (A) 10 to 90% by weight of the polyphenylene ether, (B) 90 to 10% by weight of the saturated polyester, and (C) 0. 1 to 5 parts by weight of the organic phosphorous acid compound based on 100 parts by weight of Components (A) and (B). 3. The composition according to claim 1, wherein said composition comprises (A) 20 to 80% by weight of the polyphenylene ether, (B) 80 to 20% by weight of the saturated polyester, and (C) 0. 1 to 4 parts by weight of the organic phosphorous acid compound based on 100 parts by weight of Components (A) and (B). 4. The composition according to claim 1, wherein Component (C) is selected from the group consisting of bis(nonylphenyl) pentaerythritol diphosphite, bis(2,4-di-tert-butylphenyl)pentaerythritol diphosphite and bis(2,6-di-tert-butyl-4-methylphenyl)pentaerythritol diphosphite. 5. A process for preparing the composition according to claim 1, which comprises melting and kneading Components (A), (B) and (C) and not removing partially reacted phosphite by-products and/or unreacted phosphite compounds derived from Component (C). 6. The process according to claim 5, wherein Component (C) is selected from the group consisting of bis(nonylphenyl)pentaerythritol diphosphite, bis(2,4-di-tert-butyl-phenyl)pentaerythritol diphosphite and bis(2,6-di-tert-butyl-4-methylphenyl)pentaerythritol diphosphite
