Abstract: The present invention relates to an inherently light- and heat-stabilized polyamide containing tetramethylpiperidine group of the general formula I being chemically bonded via nitrogen to a terminal polymer chain, wherein in the formula I the symbol R represents hydrogen, a hydrocarbon group containing 1 to 20 carbon atoms or a benzyl group, wherein it comprises 0.03 to 0.8 mole percent of tetramethylpiperidine, based on 1 mole of the polyamide polymer chain carboxamide groups. The invention further relates to a process for preparing such polyamide by polymerization in the presence of a tetramethylpiperidine derivative as well as the use of the polyamide for producing filaments, fibers or foils.

Abstract: 1,136,747. Cyclododecane oxime. BADISCHE ANILIN- & SODA-FABRIK A.G. 20 April, 1966 [21 April, 1965], No. 17225/66. Heading C2C. Cyclododecane is converted to its oxime by treating a solution of cyclododecane in chlorobenzene with a nitrosating agent and with light having a wavelength of 360-600 millimicrons while mixing the reaction mixture with turbulence, the cyclododecane oxime being removed from the reaction mixture outside the reaction zone by extraction with strong sulphuric acid. Suitable nitrosating agents are, for example, nitrosyl chloride or compounds which form nitrosyl chloride in the reaction medium. If desired, the process may be carried out in the presence of hydrogen chloride.
