Abstract

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.

First claim

1 . 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.

2 . Method according to claim 1 wherein the resin is an unsaturated polyester resin, a vinyl ester resin, or a (meth)acrylate resin.

3 . Method according to claim 1 wherein the metal is selected from the group consisting of Cu, Fe, and V.

4 . Accelerator solution suitable for forming a redox couple with a peroxide 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 1 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.

5 . Accelerator solution according to claim 4 wherein the metal content of said metal-bearing polymer is preferably in the range 0.01-15 wt %.

6 . Accelerator solution according to claim 4 wherein the metal is selected from the group consisting of Cu, Fe, and V.

7 . 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 metal selected from the group consisting of Cu, Mn, Fe, and V and form a complex together with said metal and a complexing agent, the second component comprising an organic peroxide.

8 . Two component composition according to claim 7 wherein the peroxide is selected from the group consisting of organic hydroperoxides, ketone peroxides, peroxycarbonates, and peroxyesters.

9 . Two component composition according to claim 7 wherein the metal is selected from the group consisting of Cu, Fe, and V.

10 . 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 1 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.

11 . Method according to claim 1 comprising the steps of 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 metal selected from the group consisting of Cu, Mn, Fe, and V 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.

12 . Method according to claim 2 wherein the metal is selected from the group consisting of Cu, Fe, and V.

13 . Accelerator solution according to claim 5 wherein the metal is selected from the group consisting of Cu, Fe, and V.

14 . Two component composition according to claim 8 wherein the metal is selected from the group consisting of Cu, Fe, and V.

15 . Method according to claim 10 , wherein the metal content of said metal-bearing polymer is in the range 0.01-15 wt %.

16 . Method according to claim 10 , wherein the metal is selected from the group consisting of Cu, Fe, and V.

17 . Method according to claim 10 , wherein the resin is an unsaturated polyester resin, a vinyl ester resin, or a (meth)acrylate resin.
