Abstract:
1. A liquid curable medium comprising: (i) from 5 to 95 wt % of an unsaturated resin; (ii) from 0.001 to 10 wt % of a peroxide; (iii) an inert or a reactive organic polar solvent; (iv) from 0.00001 and 0.02% wt % based on metal of a primary accelerator, wherein the primary accelerator is an iron or manganese complex of a tridentate, tetradentate, pentadentate or hexadentate nitrogen donor ligand in the inert or reactive organic polar solvent and, wherein the ligand is selected from the group consisting of: wherein: Q is independently selected from: p is 4; R is independently selected from: hydrogen, C1-C6-alkyl, CH2CH2OH, pyridin-2-ylmethyl, and CH2COOH; R1, R2, R3, R4, R5 and R6 are independently selected from: H, C1-C4-alkyl, and C1-C4-alkylhydroxy; wherein “R wherein: X is selected from —CH R17 independently represents a group selected from: R17 and alkyl, cycloalkyl, heterocycloalkyl, heteroaryl, aryl and arylalkyl groups optionally substituted with a substituent selected from hydroxy, alkoxy, phenoxy, carboxylate, carboxamide, carboxylic ester, sulphonate, amine, alkylamine and N and wherein at least two of R17 are —CY wherein: Q= p is 3; each R is independently selected from: hydrogen, C1-C6-alkyl, CH R1, R2, R3, and R4 are independently selected from: H, C1-C4-alkyl, and C1-C4-alkylhydroxy.
