| 摘要 | The invention relates to a stabilizer system comprising a thermal stabilizer and a supported, at least partly calcined dolomite of the formula Mt1X1*CaX2 where Mt1=Mg or Zn; X1=O or (OH)2; X2=O; (OH)2 or CO3, wherein the calcined dolomite has been supported with a metal perchlorate of the formula Mt2(ClO4)m*nH2O where Mt2=Li, Na, K, Mg, Ca, Ba, Zn, Al, La, Ce; m=1, 2 or 3, m being selected so as to compensate for the charge of the metal ion Mt2; n=0 to 3 and wherein the stabilizer system does not comprise any of the compounds selected from the group consisting of (B) and (C) when Mt1 is Mg, and wherein (B) at least one nitrogen-containing organic compound is selected from the group consisting of (B1) and (B2), (B1) being a tert-alkanolamine and (B2) being an enaminone or a urea, and (C) an alkaline earth metal aluminohydroxocarbonate of the formula (C) (M1−xZnx)yAl2(OH)4+2y CO3* zH2O (C) where M=magnesium or/and calcium; x=0 to 0.5; y=2 to 8 and z=0 to 12. The invention further relates to compositions and articles comprising the stabilizer system, to the use thereof and to processes for production of the supported dolomite. | ||

| 主权项 | 1. A stabilizer system comprising a thermal stabilizer and a supported, at least partly calcined dolomite of the formula: Mt1X1*CaX2 where Mt1=Mg or Zn; X1 =O or (OH)2; X2 =O (OH)2 or CO3, wherein the calcined dolomite has been supported with a metal perchlorate of the formula Mt2(ClO4)m*nH2O where Mt2 =Li, Na, K, Mg, Ca, Ba, Zn, Al, La, Ce; m =1, 2 or 3, m being selected so as to compensate for the charge of the metal ion Mt2; n =0 to 3, and wherein the stabilizer system does not comprise any of the compounds selected from the group consisting of (B) and (C) when Mt1is Mg, and wherein (B) is at least one nitrogen-containing organic compound and is selected from the group consisting of (B1) and (B2), (B1) being a tert-alkanolamine and (B2) being an enaminone or a urea, and (C) is an alkaline earth metal aluminohydroxocarbonate of the formula (C) (M1-xZnx)yAl2(OH)4+2y CO3* zH2O (C) where M =magnesium or/and calcium; x =0 to 0.5; y =2 to 8 and z =0 to 12. | ||
