| 摘要 |
<p>The invention relates to an organo-tin-containing complex stabiliser for synthetic resin compositions of the formula (I): M2+¿1-a-b(2+x)Al?3+a[Sn(R)(2-x)]b?(2+x)+(OH)-¿¿2-b(2+x)A?n-a/n*mH2O wherein M2+ stands for at least one divalent metal cation, R stands for a C¿1-12? linear or branched alkyl group, A?n-¿ stands for an n-valent anion or mixtures of anions, and the following conditions apply: 0∫a∫0.5; 0∫b∫0.1; 0≤x≤1; 0∫a+b(2+x)∫0.5; 0≤m≤2. The invention also relates to a method for the preparation of these stabilisers and their use in synthetic resin compositions, preferably halogen-containing synthetic resin compositions, or (co)polymers obtained by Ziegler Natta polymerization processes.</p> |
