Abstract
The present invention concerns the curing and hardening of liquids comprising unsaturated resins, a peroxide and a chelant capable of chelating at least one transition metal ion through three, four, or five nitrogen atoms, which chelants may each optionally be complexed with one or two transition metal ions, typically iron or manganese ions. The invention also provides methods and formulations for making associated compositions, compositions resultant from the curing of such liquids and associated kits comprising two or more compositions physically separated from one another, which may be used to provide curable liquids when mixed.

A composition comprising:
- (i) from 5 to 95% w/w of an unsaturated resin;
- (ii) from 0.001 to 10% w/w of a peroxide;
- (iii) from 0.00001 to 0.2% w/w of a chelant, which is of formula (III):
- wherein:
- each D is independently selected from the group consisting of thiazol-2-yl, thiazol-4-yl, pyrazin-2-yl, quinolin-2-yl, pyrazol-3-yl, pyrazol-1-yl, pyrrol-2-yl, imidazol-2-yl, imidazol-4-yl, benzimidazol-2-yl, pyrimidin-2-yl, 1,2,4-triazol-3-yl, 1,2,4-triazol-1-yl, 1,2,3-triazol-1-yl, 1,2,3-triazol-2-yl and 1,2,3-triazol-4-yl, each of which may be optionally substituted by one or more groups independently selected from the group consisting of —F, —Cl, —Br, —OH, —OC1-C4alkyl, —NH—CO—H, —NH—CO—C1-C4alkyl, —NH2, —NH—C1-C4alkyl, and —C1-C4alkyl;
- R1 and each R2 are independently selected from the group consisting of C1-C24alkyl, C6-10arylC1-C6alkyl, C6-10aryl, C5-C10heteroarylC1-C6alkyl, each of which may be optionally substituted by one or more groups selected from —F, —Cl, —Br, —OH, —OC1-C4alkyl, —NH—CO—H, —NH—CO—C1-C4alkyl, —NH2, —NH—C1-C4alkyl and —SC1-C4alkyl;
- and CH2CH2N(R8)(R9),
- wherein N(R8)(R9) is selected from the group consisting of di(C1-44alkyl)amino;
- di(C6-10aryl)amino in which each of the aryl groups is independently optionally substituted with one or more C1-20alkyl groups;
- di(C6-10arylC1-6alkyl)amino in which each of the aryl groups is independently optionally substituted with one or more C1-20alkyl groups;
- NR7, in which R7 and the nitrogen atom N to which it is attached represent a heterocycloalkyl group optionally substituted with one or more C1-20alkyl groups, which is connected to the remainder of R1 or R2 through the nitrogen atom N;
- di(heterocycloalkylC1-6alkyl)amino, in which each of the heterocycloalkyl groups is independently optionally substituted with one or more C1-20alkyl groups;
- and di(heteroarylC1-6alkyl)amino, wherein each of the heteroaryl groups is independently optionally substituted with one or more C1-20alkyl groups;
- R3 and R4 are independently selected from hydrogen, C1-C8alkyl, C1-C8alkyl-O—C1-C8alkyl, C6-C10aryloxyC1-C8alkyl, C6-C10aryl, C1-C8hydroxyalkyl, C6-C10arylC1-C6alkyl and C5-C10heteroarylC1-C6alkyl, and —(CH2)0-4C(O)OR5 wherein R5 is independently selected from:
- hydrogen, C1-C8alkyl and C6-10aryl;
- and
- X is selected from C═O, —[C(R6)2]0-3- wherein each R6 is independently selected from hydrogen, hydroxyl, C1-C4alkoxy and C1-C4alkyl
