| titleOfInvention | NEW CYCLIC POLYIMINOETHER (II) |
| abstract | The cyclic polyiminoethers described are bis-, tris- or tetrakis-isoxazolines of the formula (I), in which n is 2, 3 or 4; A is a carbonyl group or the acyl unit of a di-, tri- or tetracarboxylic acid with 2 to 20 C-atoms; R is hydrogen or an alkyl, alkenyl or aryl group with not more than 12 C-atoms; M is a direct linkage or a double-bonded group with not more than 12 C-atoms, selected from the group comprising alkylene, alkenylene, arylene and alkylarylene, which may contain ether oxygen atoms in the carbon chain, whereby R and M may be substituted by alkoxy groups with 1 to 3 C-atoms. The new polyiminoethers can be prepared in almost quantitative yields from polycarboxylic-acid esters of the formula (II): A(-O-R')n, in which A and n are as defined above and R' is an alkyl group with 1 to 4 C-atoms, by an ester interchange reaction with n moles of a hydroxyoxazoline of the formula (III), in which all the symbols are as defined above. The polyiminoethers described are intermediates with a wide range of applications. A preferred field of application is in processes for the production of cross-linked polymers, the polyiminoethers being used alone, or preferably together with other low-molecular or polymeric starting materials. Particularly preferred are polymeric coatings, consisting of the bis-, tris- or tetrakis-isoxazolines described, on rigid substrates. Such coatings have shown themselves to be extremely resistant to the action of light and solvents. |
