Method for curing a radically curable resin
View Patent ↗Method for curing a radically curable resin by adding to said resin an organic peroxide and a metal-bearing polymer, said metal-bearing polymer comprising functional groups that coordinate to a metal selected from the group consisting of Cu, Mn, Fe, and V and form a complex together with said metal and a complexing agent.
1. A method for curing a radically curable resin, the method comprising adding to said resin an organic peroxide and a metal-bearing polymer, said metal-bearing polymer comprising functional groups that coordinate to a Cu, Mn, Fe, or V metal and form a complex together with said metal and a complexing agent, wherein the radically curable resin is an unsaturated polyester resin or a vinyl ester resin.
2. The method according to claim 1 wherein the metal is Cu, Fe, or V.
3. A two-component composition comprising a first component and a second component, the first component comprising a radically curable resin and a metal-bearing polymer comprising functional groups that coordinate to a Cu, Mn, Fe, or V metal and form a complex together with said metal and a complexing agent, the second component comprising an organic peroxide, wherein the radically curable resin is an unsaturated polyester resin or a vinyl ester resin.
4. The two component composition according to claim 3 wherein the peroxide is an organic hydroperoxides, a ketone peroxide, a peroxycarbonate, or a peroxyester.
5. The two component composition according to claim 3 wherein the metal is selected Cu, Fe, and or V.
6. The method according to claim 1 wherein the metal-bearing polymer is added to the resin in the form of an accelerator solution suitable for forming a redox couple with a peroxide, the accelerator solution comprising:
at least one solvent selected from compounds with the formulae P(R) 3 , P(R) 3 ═O, and HO—(—CH 2 —C(R 1 ) 2 —(CH 2 ) m —O—) n —R 2 , wherein each R is independently selected from hydrogen, alkyl with 1 to 10 carbon atoms, and alkoxy groups with 1 to 10 carbon atoms, each R l is independently selected from the group consisting of hydrogen, alkyl groups with 1-10 carbon atoms, and hydroxyalkyl groups with 1 to 10 carbon atoms, n=1-10, m=0 or 1, and R 2 is hydrogen or an alkyl group with 1-10 carbon atoms, and
a metal-bearing polymer, said metal-bearing polymer comprising functional groups that coordinate to a metal selected from the group consisting of Cu, Mn, Fe, and V and form a complex together with said metal and a complexing agent.
7. The method according to claim 1 comprising providing a two-component composition comprising a first component and a second component, the first component comprising a radically curable resin and a metal-bearing polymer comprising functional groups that coordinate to a Cu, Mn, Fe, or V metal and form a complex together with said metal and a complexing agent, the second component comprising an organic peroxide, and mixing the first component with the second component, wherein the radically curable resin is an unsaturated polyester resin or a vinyl ester resin.
8. The two component composition according to claim 4 wherein the metal is Cu, Fe, or V.
9. The method according to claim 6 wherein the metal content of said metal-bearing polymer is in the range 0.01-15 wt %.
10. The method according to claim 6 , wherein the metal is selected Cu, Fe, or V.
11. The method according to claim 7 wherein the organic peroxide is an organic hydroperoxide, a ketone peroxide, a peroxycarbonate, or a peroxyester.
