Chlorine contg. resin compsns

一种含氯树脂组合物，是在含氯树脂组合物中通过同时添加2-巯基苯并噻唑和苯并三唑系化合物，可以同时提高含氯树脂组合物的热稳定性和色相，改善含氯树脂制品加工时由于热加工引起的物性劣化，在100重量份的含氯树脂中含有水滑石和β-二酮类、2-巯基苯并噻唑0.0001～5.0重量份和苯并三唑0.001～5.0重量份。 PURPOSE: Provided is a chlorine-containing resin composition to improve both heat stability and coloring prevention property by adding 2-mercaptobenzothiazole in combination with a benzotriazole-based compound to the chlorine-containing resin composition. CONSTITUTION: The stabilized chlorine-containing resin composition contains chlorine-containing resin; hydrotalcites represented by the following formula; β-diketones; and stabilizing additive containing (a) 0.0001 to 5.0 weight parts of 2-mercaptobenzothiazole represented by the following formula (2), and (b) 0.001 to 5.0 weight parts of benzotriazole-based compound based on 100 weight parts of the chlorine-containing resin represented by formula 1, (M¬2+)1-xAlx(OH)2(A¬n-)x/n¡ mH2O, where M¬2+ represents Mg or (Mg+Zn), and Mg>Zn provided that M¬2+ is (Mg+Zn), x is in a range of 0
