| abstract | A 1,6-diazaspiro[4,4]nonane-2,7-dione derivative having the nformula I: n X nB-YP-Y nB-X (I) nin which B has the formula II: n nwherein n a) Z₁, Z₂, Z₃, Z₄ are independently n- C(Z′)₂ in which Z′ independently is hydrogen or C₁₋₄ alkyl, or n- such that two adjacent Z atoms form part of a benzene ring; b) each R is independently a bivalent group of the formula III or nIV: n n n nwherein A is a substituent replacing hydrogen selected nindependently from a C₁₋₄ alkyl or halogen atom, n independently is n0, 1 or 2 and the free valence bond of C* is linked with a ring nnitrogen atom of the spirodilactam of the formula II; c) m ≧ 0; d) each X independently is hydrogen or a glycidyl-, acrylyl-, nmethacrylyl-, allyl- or propargyl group, with the proviso that when nX is acrylyl, methacrylyl, allyl or propargyl then m is 0; e) Y is 2-hydroxy-1,3-propadiyl; f) each P independently is a divalent radical derived from a ndihydric aromatic alcohol; g) p is on average of from 0 to 3; nwith the proviso that when R is a bivalent group of the formula III nand simultaneously Z₂ and Z₃ are each CH₂ and simultaneously Z₁ and nZ₄ are each independently hydrogen or a C₁₋₄ alkyl, then each X is nnot hydrogen or glycidyl. |
