Patent Number Title Of Patent Date Issued
4393218 2,2,4,5,5-Pentamethyl-3-formyl-.DELTA..sup.3 -pyrroline and the preparation thereof July 12, 1983
A process for preparing 2,2-dialkyl-4-methyl-5,5-dialkyl-3-formyl-.DELTA..sup.3 -pyrrolines by reacting the corresponding dialkyl substituted di-tert-propargylamines with water at a pH equal to or less than 3.0. Preferably, an inorganic mercury compound is used as a catalyst.
4346188 Polyolefin compositions stabilized against UV-radiations by pyrrolidine derivatives August 24, 1982
Polyolefin polymers can successfully be stabilized against the detrimental effects of UV-radiations by compounding them with a stabilizer belonging to the class of compounds containing a pyrrolidine ring and which are sterically hindered in the 3-position and also substituted in such
4325864 Pyrrolidine-ring-containing compositions for use as anti-UV stabilizers in plastics materials April 20, 1982
For stabilizing polyolefin polymers such as polyethylene and polypropylene against the detrimental effects of exposure to UV-radiations and weathering agents, a stabilizing additive is disclosed which consist of a fatty acid ester of the N-(beta-hydroxyethyl)-2,2,3,4,5,5-hexamethylpy
4321190 Polyolefin compositions stabilized against UV light radiations with open-chain hindered amines March 23, 1982
This invention relates to particular polyolefin compositions which contain, as stabilizers against UV-light radiations, open-chain amine compounds which are hindered in the alpha-position by alkyl radicals, said amine compounds corresponding to the following general formula: ##STR1##
