Abstract
Benzophenone iminodiimides of the formula I ##STR1## in which Y denotes hydroxyl or carboxyl, R.sub.1 denotes the optionally substituted radicals alkylene, phenylene or benzylidene, R.sub.2 denotes the radicals OH, substituted or unsubstituted alkyl or NH--CO--NHR.sub.3 and R.sub.3 denotes the radicals H, alkyl, phenyl or benzyl, processes for their preparation and polymers prepared therefrom.
Claims3
Compounds of the formula I ##STR10## in which Y denotes hydroxyl or carboxyl, R.sub.1 denotes a straight-chain or branched alkylene radical having 1 to 6 C atoms, or an o-, m- or p-phenylene or benzylidene radical which is optionally substituted by Cl, lower alkyl or lower alkoxy, and R.sub.2 denotes the radical OH, a straight-chain or branched, saturated or mono- or polyunsaturated alkyl radical having 1 to 20 C atoms, which can be substituted by Cl, OH, NH.sub.2, CONH.sub.2 or COOR.sub.3, or a radical of the formula NH--CO-NHR.sub.3, wherein R.sub.3 can be hydrogen, an alkyl radical having 1 to 4 C atoms or a phenyl or benzyl radical.
