Abstract: 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 compounds are prepared by reaction of camphene with alcohols R--OH, in which R represents one of the above-mentioned radicals. 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
