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 invention provides derivatives of polyalkyl-1-oxa-diaza-spirodecanes prepared from compounds of the formula ##STR1## in which X is ##STR2## and mono- or dihalo-hydrocarbons by alkylation at the nitrogen atom of the 5-membered ring, and the salts thereof. The novel compounds are migration-resistant light stabilizers of low volatility for synthetic polymers.

摘要:
In the synthesis of 2,2,6,6-tetramethylpiperidone-4 (triacetone-amine) from acetone and ammonia, a partially halogenated or perhalogenated aliphatic or cyclic hydrocarbon is used as catalyst in an amount of from 0.01 to 5 mol %, relative to acetone.
