Abstract

A crosslinkable surfactant useful for preparing an emulsion polymerization composition; the crosslinkable surfactant including (a) a crosslinkable functionality and a hydrophobic tail with a Tung oil derivative structure, and (b) a polyalkylene oxide or polyglycerin part as hydrophilic head; an emulsion polymerization process using the crosslinkable surfactant; an emulsion polymerization composition; and a process for preparing the emulsion polymerization composition.

First claim

What is claimed is:

1. A monomer emulsion composition comprising a pre-emulsion of: a crosslinkable surfactant comprising a reaction product of (a) Tung oil acid and (b) at least one alkylene oxide forming a Tung oil derivative, wherein the Tung oil derivative has the following chemical Structure (II):

wherein R is hydrogen, SO 3 − or PO 3 − , R′ is hydrogen or C1-C6 alkyl group, and n is a number value of from 1 to 15; or

wherein R 1 and R 2 , each individually, is an alkyl having from C1 to about C10 carbon atoms, an aryl having from C5 to about C10 carbon atoms, a polyol, a polyol ester, hydrogen, SO 3 − , or PO 3 − , and wherein R 1 and R 2 can be the same or different;
at least one monomer; and
water.

2. The monomer emulsion composition of claim 1 , wherein the alkylene oxide is selected from the group consisting of ethylene oxide, propylene oxide, butylene oxide, and mixtures thereof.

3. The monomer emulsion composition of claim 1 , wherein the Tung oil derivative has a combined crosslinkable functionality and hydrophobic chain as a Tung oil structure.

4. The monomer emulsion composition of claim 1 , wherein the Tung oil derivative has a hydrophilic chain with a polyalkylene oxide glycol derivative or a polyglycerin derivative.

5. The monomer emulsion composition of claim 1 , wherein the Tung oil derivative is an ionic form.

6. The monomer emulsion composition of claim 1 , wherein the at least one monomer is selected from the group consisting of styrene, butyl acrylate, and mixtures thereof.

7. The emulsion polymerization composition of claim 1 further comprising at least one initiator.

8. The emulsion polymerization composition of claim 7 , wherein the at least one initiator is selected from group consisting of potassium persulfate, ammonium persulfate, benzoyl peroxide; and mixtures thereof.

9. A polymerization reaction product made from the emulsion polymerization composition of claim 7 .

10. The polymerization reaction product of claim 9 , wherein the reaction product is a film or a coating.

11. The film or coating of claim 10 , wherein the film or coating exhibits a water whitening resistance property having a luminosity value L from about 45 to about 48.

12. A process for preparing a crosslinkable surfactant comprising reacting (a) Tung oil acid and (b) at least one alkylene oxide forming a Tung oil derivative, wherein the Tung oil derivative has the following chemical Structure (II):

wherein R is hydrogen, SO 3 − , or PO 3 − R′ is hydrogen or C1-C6 alkyl group, and n is a number value of from 1 to 15; or

wherein R 1 and R 2 , each individually, is an alkyl having from C1 to about C10 carbon atoms, an aryl having from C5 to about C10 carbon atoms, a polyol, a polyol ester, hydrogen, SO 3 − , or PO 3 − ; and wherein R 1 and R 2 can be the same or different.

13. A process for preparing a monomer emulsion composition comprising admixing (a) the crosslinkable surfactant comprising the Tung oil derivative of claim 1 ; (b) at least one monomer; and (c) water.

14. A process for preparing an emulsion polymerization composition comprising admixing (a) the pre-emulsion of claim 1 ; and (b) at least one initiator.
