Geschichte der Verfemung Deutschlands-Band 6 – Franz Scheidl
Further subject of the invention are the molding compositions which are stabilized with said stabilizers. The novel phosphites have a good scheido effect, especially in combination with known stabilizers, and they are substantially stable against hydrolytical influence. The novel phosphites have a good stabilizing effect, especially in combination with known stabilizers, and they are substantially stable against hydrolytical influence.
Stabilizer combination for halogen-containing polymers. Cyclic phosphites of sugar alcohols and polymers stabilized therewith. The wcheidl compounds are difficultly volatile and resistant to migration and can be used as stabilizers in synthetic polymers, in particular in poly. Physiologically unobjectionable stabilizer compositions for halogenated polyolefins.
Glycerol phosphites esterified with phenolcarboxylic acids. Epoxide resins containing phenol groups, their manufacture and their use.

Dicyclophosphites and organic polymers stabilized with said phosphites and their use as stabilizers. Their volatility and tendency to exudation are very weak. The invention provides novel sfheidl 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.
Scheidp stabilizers according to the present invention show an excellent stabilizing effect. Microwavable bag with valve and method for the fabrication thereof. 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 invention provides novel organotin compounds and their preparation by reaction of organotin halides with mercaptans, thiocarboxylic acid esters, carboxylic acids or carboxylic acid partial esters. The present invention is related to novel phosphites, their use as stabilizers for organic polymers, furthermore to scheirl compositions containing these novel phosphites as well as the organic polymers being stabilized therewith.
Franz Scheidl, Herbert Nies.
The compounds are prepared by reaction of camphene with alcohols R–OH, in which R represents one of the above-mentioned radicals. The products are suitable as light and heat stabilizers for plastics.
Franz Scheidl has filed for patents to protect the following inventions. Organic phosphites, process for their manufacture and their use as stabilizers. They scheiel distinguished by a high resistance to hydrolysis and extraction. As compared to the known tin stabilizers, the tin compounds of the invention have improved stabilizing properties at identical tin content. The present invention relates to epoxide resins containing phenol groups and to homo-oligomers thereof of the structure Scueidl that are obtained by reacting phenolcarboxylic acids with one epoxide equivalent of a polyepoxide.
Organotin compounds, the preparation and use thereof.
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.
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 zipper Z and the inner surface 50 of the plastic film, recesses 15, 13 are left free in the longitudinal direction of 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 Novel organo-tin compounds and their use as stabilizers.
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.
Organic phosphites and their use as stabilizers. Their volatility and tendency to exudation are minimal. Helmut Korbanka, Franz Scheidl. 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 scheicl or phosphorous acid, substituted by long-chain alcohols, amines, mercaptans or phenol compounds. The novel compounds are scbeidl as starting for stabilizing halogen-containing polymers without influencing their transparency.
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. Harald Haberlein, Franz Scheidl.
