摘要:
The present invention provides novel organo-tin compounds of the formula ##STR1## AND THEIR USE AS STABILIZERS FOR HALOGEN CONTAINING POLYMERS. As compared to the known tin stabilizers, the tin compounds of the invention have improved stabilizing properties at identical tin content.
摘要:
The present invention is related to novel phosphites, their use as stabilizers for organic polymers, furthermore to stabilizer compositions containing these novel phosphites as well as the organic polymers being stabilized therewith. The novel phosphites have a good stabilization effect, especially in combination with known stabilizers, and they are substantially stable against hydrolytical influence. Their volatility and tendency to exudation are very weak.

摘要:
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 polyepoxide. The new compounds are difficultly volatile and resistant to migration and can be used as stabilizers in synthetic polymers, in particular in poly-.alpha.-olefins.

摘要:
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 products are suitable as light and heat stabilizers for plastics. They are distinguished by a high resistance to hydrolysis and extraction.
摘要:
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 (20), wherein 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 (50), through 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 (20).
摘要:
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. Suitable organotin halides are those obtained by reaction of Sn+HCl with an olefin which carries a carbonyl group in adjacent position to the olefinic double bond and which is substituted in addition by at least one carboxylate group not adjacent to the double bond.The novel compounds are used as starting for stabilizing halogen-containing polymers without influencing their transparency.

Halogen-containing polymers are heat-stabilized by physiologically unobjectionable mixtures consisting of 10 to 70% by weight of an aluminum salt, 10 to 80% by weight of a calcium salt and 10 to 70% by weight of a zinc salt of an aliphatic mono- or dicarboxylic acid or an aromatic mono-, di-, or tricarboxylic acid.
