Abstract

Embodiments of the present disclosure are directed towards functionalized oligomers. As an example, a functionalized oligomer can be represented of Formula (I): (Formula I) in which R 1 is a structure of Formula II: (Formula II) and R 2 has a formula —CxHyO—, wherein n is an integer having a value from 2 to 6, m is an integer having a value from 2 to 10, X independently is an integer having a value from 1 to 12, and Y is an integer having a value from 2 to 24.

First claim

What is claimed:

1. A functionalized oligomer of Formula (I):

in which R 1 is a structure of Formula IV:

and R 2 has a formula —C X H Y O—, wherein n has a value of 2, m is an integer having a value from 3 to 4, b has a value of 3 to 4, X has a value of 2, and Y has a value of 4.

2. An open-cell foam forming composition comprising:
a functionalized oligomer of claim 1 ; and
a multifunctional Michael acceptor.

3. The composition of claim 2 , wherein the functionalized oligomer has an equivalent weight of 200 grams/equivalent to 5000 grams/equivalent.

4. The composition of claim 2 , wherein the multifunctional Michael acceptor is a multifunctional acrylate.

5. The composition of claim 4 , wherein the multifunctional acrylate is selected from the group of trimethyloipropanetri-acrylate, pentaerythritoltetra-acrylate, di-trimethylolpropanetertra-acrylate, di-pentaerythritolhexa-acrylate, di-pentaerthritolpenta-acrylate, diacrylate of diglycidyl ether bisphenol-A, ethoxylated trimethylolpropane triacrylate, tricyclodecanedimethanol diacrylate, cyclohexanedimethanol diacrylate, and combinations thereof.

6. The composition of claim 2 , wherein multifunctional Michael acceptor functionalities and functionalized oligomer functionalities have a molar ratio of 0.5:3.0 to 3.0:0.5 moles of multifunctional Michael acceptor functionalities to moles of the functionalized oligomer functionalities.

7. The composition of claim 2 , including a catalyst having a concentration of 0.01 moles of catalyst per equivalent of functionalized oligomer functionalities percent to 1 mole of catalyst per equivalent of functionalized oligomer functionalities.

8. The composition of claim 7 , wherein the catalyst is selected from the group of 1,1,3,3-tetramethylguanidine, 1,8-diazabicyclo[5.4.0]undec-7-ene, 1,5-diazabicyclo[4.3.0]non-5-ene, tetramethylammonium hydroxide, (2-hydroxyethyl)trimethylammonium hydroxide, potassium carbonate, potassium phosphate, potassium phenoxide, sodium phenoxide, tertraethylammonium hydroxide, and combinations thereof.

9. The composition of claim 2 , including a blowing agent having a concentration of 0.5 weight percent to 50 weight percent based upon a total weight of the functionalized oligomer and the multifunctional Michael acceptor.

10. The composition of claim 9 , wherein the blowing agent is selected from the group of cyclopentane, n-pentane, formaldehyde dimethylacetal, methylformate, methyl butane, 1,1,2,2,3-pentafluoropropane, 1,1,1,3,3-pentafluoropropane, 1,1,1,3,3-pentafluorobutane, 1,1,1,2,3,4,4,5,5,5-decafluoropentane, and combinations thereof.

11. The composition of claim 2 , including a surfactant having a concentration of 0.1 weight percent to 5.0 weight percent based upon a total weight of the functionalized oligomer and the multifunctional Michael acceptor.

12. An open-cell foam that is a reaction product of open-cell foam forming composition of claim 2 .
