Abstract: The invention relates to carbonated alkaline earth metal carboxylates that are neutral, meaning they have a base value of less than 10 mg KOH/g, and that are derived from a mixture of, preferably branched, optionally cyclic, C4-C40 alk(en)yl carboxylic acids and C6-C30 alkaryl or aralkyl carboxylic acids. Also a process to make such products is claimed, as well as the use of the products to stabilize PVC.

Abstract: The invention relates to a organo-tin-containing complex stabilizer for synthetic resin compositions of the formula I:M.sup.2+.sub.1-a-b(2+x) Al.sup.3+.sub.a [Sn(R).sub.(2-x) ].sub.b.sup.(2+x)+ (OH).sup.-.sub.2-b(2+x) A.sup.n-.sub.a/n *mH.sub.2 O (I)wherein M.sup.2+ stands for at least one divalent metal cation, R stands for a C.sub.1-12 linear or branched alkyl group, A.sup.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.ltoreq.x.ltoreq.1; 0<a+b(2+x)<0.5; 0.ltoreq.m.ltoreq.2.The invention also relates to a method for the preparation of these stabilizers and their use in synthetic resin compositions, preferably halogen-containing synthetic resin compositions, or (co)polymers obtained by Ziegler Natta polymerization processes.

Abstract: The present invention relates to a composition based on polymer and/or co-polymers of vinyl chloride including organotin salts and/or one or more divalent metal salts of a carboxylic acid or phenol, and one or more metal salts of the organic compounds of general formula A: ##STR1## in which R.sub.1 represents a linear or branched alkylene or alkenylene radical having up to 20 carbon atoms, an aralkylene radical having from 7 to 20 carbon atoms or an arylene or cycloalkylene radical having from 6 to 20 carbon atoms, the cycloalkylene radicals optionally containing carbon--carbon double bonds; these radicals optionally being unsubstituted or substituted for example by one or more or halogen atoms or hydroxyl groups or, for aryl or cycloalkylene radicals, by one or more methyl, ethyl or methoxy radicals, the above-mentioned radicals optionally modified by the presence in an aliphatic chain of one or more --O--, --CO-- or CO.sub.2 -chain members or N; R.sub.2 represents O,S,NR.sub.5 or NNHR.sub.5 wherein R.sub.
