Abstract: The invention relates to the use of triazenes of formula (I) wherein Q is a direct bond or a bivalent radical —(CR8R9)—, Z1 is —O—, —NR10—, —CH2—, —(CR11R12)— or —C(?O)— and R1 to R12 are optionally substituted hydrocarbon residues, as precursors for radicals useful in reactions triggered by free radicals, such as polymerization of unsaturated monomers and degradation of polyolefins. Most of the triazenes of formula (I) are novel and claimed, too, as well as the preparation of triazenes of formula (I) and polymerisable compositions comprising them.

Abstract: The invention relates to novel O-dialkylamino-isoureas and polymerizable compositions comprising these O-dialkylamino-isoureas of compounds of the general formula (I). The invention further relates to the use of O-dialkylamino-isoureas as polymerization initiators, especially to prepare coatings or for controlled degradation of polyolefins.

Abstract: The present invention provides organometallic latent catalyst compounds, which are suitable as catalysts in polyaddition or polycondensation reactions which are catalysed by a Lewis acid type catalyst, in particular for the crosslinking of a blocked or unblocked isocyanate or isothiocyanate component with a polyol or polythiolto form a polyurethane (PU).

Abstract: Radiation-curable acrylated polyaminoamides obtainable by Michael addition of polyaminoamides containing terminal amine groups (A) and polyolester acrylates (B), the molar ratio of the acrylate groups in the polyolester acrylates (B) to the aminohydrogen groups in the polyaminoamides (A) being at least 1:1, characterized in that the polyaminoamides have an amine value above 115, are suitable as radiation-curable compounds for the production of coatings.

Abstract: Acrylated polyaminoamides obtainable by Michael addition of polyaminoamides containing terminal amine groups (A) and polyolester acrylates (B) which contain at least 8 acrylate groups per molecule, the molar ratio of the acrylate groups in the polyolester acrylates (B) to the aminohydrogen groups in the polyaminoamides (A) being at least 8:1, are suitable as radiation-curable compounds for the production of coatings.

Abstract: Radiation-curable acrylated polyaminoamides obtainable by Michael addition of polyaminoamides containing terminal amine groups (A) and polyolester acrylates (B), the molar ratio of the acrylate groups in the polyolester acrylates (B) to the aminohydrogen groups in the polyaminoamides (A) being at least 1:1, characterized in that polyolester acrylates (B) are acrylated addition products of propylene oxide onto trimethylol propane, are suitable as radiation-curable compounds for the production of coatings.
