Helmut Korbanka, Franz Scheidl. The invention provides novel organotin compounds and their preparation by reaction of organotin halides with mercaptans, thiocarboxylic acid esters, carboxylic fraanz or carboxylic acid partial esters. The invention relates to new terpene ethers of the formula STR1 in which R denotes a cyclic or bicyclic radical or an alkyl radical which is substituted by cyclic, bicyclic or tricyclic radicals, optionally via an oxygen bridge.
The present invention is related to novel phosphites, their use as stabilizers for organic polymers, furthermore to stabilizer scheeidl containing these novel phosphites as well as the organic polymers being stabilized therewith.

The products are suitable as light and heat stabilizers for plastics. The present invention is related to stabilizer compositions for the stabilization of molding compositions based on halogenated polyolefins, essentially consisting of aluminum salts of certain carboxylic acids, organic phosphites and substituted indoles.
The invention provides novel organotin halides obtained by reaction of tin and hydrogen chloride with those olefins which carry a carbonyl group in adjacent position to the olefinic double bond and which are substituted in addition by at least one carboxylate group not adjacent to the double bond.
Physiologically unobjectionable stabilizer compositions for halogenated polyolefins. In a reclosable bag 20 a zipper Z is provided on the inner surfaces 50 of the plastic film and the two parts of the zipper Z are fixed on the opposite inner surfaces 50 of the bag 20wherein the zipper Z is connected to the inner surface 50 of the plastic film in such a manner that between the welded regions 12, 14 between the frnz Z and the inner surface 50 of the plastic film, recesses 15, 13 are left free in the longitudinal direction acheidl the zipper Z to form a seal-free longitudinal channel and in the transverse direction of the zipper Z to produce free air or steam passage openings at defined distances between the zipper Z and the inner surface 50through which openings a passage of steam is possible, wherein ends of the openings facing the interior 60 of the bag 20 are larger than ends of the openings facing the exterior 70 of the bag Their volatility and tendency to exudation are minimal.
The novel phosphites have a good scheid effect, especially in combination with known stabilizers, and they are substantially stable against hydrolytical influence. The present invention relates to epoxide resins containing phenol groups and to homo-oligomers thereof of the structure STR1 that are obtained by reacting phenolcarboxylic acids with one epoxide equivalent of a scneidl. Harald Haberlein, Franz Scheidl.
They are distinguished by a high resistance to hydrolysis and extraction. The compounds are prepared by reaction of camphene with alcohols R–OH, in which R represents one of the above-mentioned radicals. Organic phosphites, process for their manufacture and their use as stabilizers.
The novel compounds are used scheldl starting for stabilizing halogen-containing polymers without influencing their transparency.
Their volatility and tendency to exudation are very weak. Epoxide resins containing phenol groups, their manufacture and their use. The stabilizers according to the present invention show an excellent stabilizing effect. The novel phosphites have a good stabilization effect, especially in combination with known stabilizers, and they are substantially stable against hydrolytical influence. The invention is related to novel phosphites of sugar alcohols, their use as stabilizers for organic polymers, furthermore to stabilizer compositions containing these novel phosphites as well as the organic polymers stabilized therewith.

Further subject of the invention are the molding compositions which are stabilized with said stabilizers. Organotin compounds, the preparation and use thereof. Dicyclophosphites and organic polymers stabilized with said phosphites and their use as stabilizers. The invention provides novel esters of glycerol, in which one of the OH groups of the glycerol is esterified with a phenolcarboxylic acid, while the two other OH groups are esterified with phosphoric or phosphorous acid, substituted by long-chain alcohols, amines, mercaptans or phenol compounds.
The new ethers are used in the field of aroma substances and solvents, and as intermediates for plant protection agents, agents for combating pests and medicaments.
