Abstract
Fluorine-containing maleic and derivative of the formula ##STR1## WHEREIN A DENOTES 1 OR 2 AND R denotes either the radical --NH.multidot.CO--D--CO.multidot.OH or the radical ##STR2## wherein D represents a divalent radical containing a carbon-carbon double bond, and in which b denotes a number from 3 to 5 if a = 1, or b denotes 3 or 4 if a = 2, and if a = 2 the two radicals R are preferably in the p- or in the m-position to one another, are prepared. These compound are useful for preparing high polymers with good heat resistance.
