摘要： Novel compounds according to the present invention, i.e. derivatives of .alpha.,.omega.-bis-alkyl esters of isobutyric acid having the formula: ##STR1## A method for preparing the above-specified novel compounds consists in reacting .alpha.,.alpha.'-azo-bis-isobutyric acid dinitrile and a saturated alkyl monohydric alcohol derivative of the formula ROH, wherein R: ##STR2## with gaseous hydrogen chloride in an organic solvent medium in the presence of 0.5-5% by mass of a water-soluble ether at a temperature within the range of from -5.degree. to +6.degree. C., followed by treating the resulting reaction mixture with water at a temperature of from 0.degree. to -5.degree. C. and isolation of the desired product.The novel compounds according to the present invention are useful as initiators for a radical-type polymerization of ethylenically unsaturated compounds, as well as the starting products for the manufacture of reactive polymers by a simplified process.
