| 摘要 |
The invention relates to hardenable compositions which contain as the essential constituent, in the non-hardened condition, at least one phosphazene derivative of the general formula [NP-(X-Y-Z)2]n, and at least one cross-linking agent with at least two functional groups which are selected among the Z radicals and which can react with the functional Z radicals of the phosphazene derivative is provided, wherein X radicals are from the group -O-, -S-, -NH- or -NR-, preferably oxygen, Y are aliphatic, cycloaliphatic, aromatic and/or heteroaromatic hydrocarbon groups, Z are functional radicals from the group -OH, -NH2, -NCO, -COOH, -CHO, -CH=CH2, allyl, N-methylol, acrylate, methacrylate, silyl, glycidyl or epoxy or preliminary stages of the radicals from this group or radicals from this group which are blocked by protective groups, preferably acrylate or methacylrate radicals and n is an integer of at least 3 and no more than 10; The NP radicals of the above formula are preferably combined to a phosphazene ring, n being 3 or 4. The phophazene derivatives can be used for the production of hardenable lacquers, coating agents or fillers, knifing fillers, adhesives, preforms or foils.
