The invention relates to a process for the production of even-series .omega.-amino acids of the general formula NH2(CH2CH2)nCH2COOH /I/, where n = 1 or 2. The process of the invention comprises telomerizing ethylene with methyl esters of halogen acetic acids of the general empirical formula XmCH3-mCOOCH3 /II/, where X = Br and M = 1 or X = Cl and M = = 2 or 3, at a temperature of from 100 to 145°C. and under ethylene pressure of from 25 to 40 gage atm. in the presence of initiators of free-radical reactions. The telomerization produces telomers of the general empirical formula CH3OOCCH3-m Xm-1(CH2CH2)nX /III/, where X, N and M are the same as in the formulas given hereabove. In case X = Br …
