Abstract

Initiator systems of the present invention include both a complexed initiator and a carboxylic acid decomplexer. For example, dicarboxylic acid decomplexer, carboxylic acid ester decomplexers, and monocarboxylic acid decomplexers (preferably those comprising an alkyl group having at least nine carbon atoms for low odor compositions) are useful in the present invention.

Claims

1. A method of initiating polymerization, comprising:

providing a complexed initiator; and

reacting a decomplexer with the complexed initiator, the decomplexer having a structure represented by (I);

wherein;

R¹ is selected from the group consisting of hydrogen, a monovalent organic group, and a multivalent organic group;

R² is a multivalent organic group;

R³ is selected from the group consisting of hydrogen and a monovalent organic group;

m is an integer of 0-2; and

n is an integer greater than or equal to one.

2. The method of claim 1, wherein the decomplexer is a dicarboxylic acid decomplexer.

3. The method of claim 1, wherein the decomplexer is a carboxylic acid ester decomplexer.

4. An initiator system capable of initiating polymerization, comprising:

a complexed initiator;

a carboxylic acid decomplexer of claim 1; and

a second decomplexer.

5. The initiator system of claim 4, wherein the second decomplexer comprises an anhydride decomplexer.

6. The initiator system of claim 5, wherein the second decomplexer is selected from the group consisting of methacrylic anhydride, succinic anhydride, maleic anhydride, and glutaric anhydride.

7. An initiator system of claim 1, wherein the complexed initiator is an organoborane amine complex.

12. The method of claim 1 wherein the complexed initiator and the decomplexer react in the presence of at least one polymerizable monomer in order to form a polymerized composition.

8. A kit comprising:

a polymerizable composition, wherein the polymerizable composition comprises;

at least one polymerizable monomer, and

a first decomplexer, comprising a carboxylic acid decomplexer having a structure represented by (I);

wherein;

R¹ is selected from the group consisting of hydrogen, a monovalent organic group, and a multivalent organic group;

R² is a multivalent organic group;

R³ is selected from the group consisting of hydrogen and a monovalent organic group;

m is an integer of 0-2;

n is an integer greater than or equal to one;

a second decomplexer; and

an initiator component, wherein the initiator component comprises;

a complexed initiator, and

an optional diluent.

9. The kit according to claim 8, wherein the second decomplexer comprises an anhydride decomplexer.

10. The kit according to claim 8, wherein the second decomplexer is selected from the group consisting of methacrylic anhydride, succinic anhydride, maleic anhydride, and glutaric anhydride.

11. The kit according to claim 8, further comprising a multi-part dispenser.
