Abstract

A polymer composition comprising a linear ultraviolet radiation absorbing polyether that comprises a chemically bound UV-chromophore.

First claim

The invention claimed is:

1. A polymer composition comprising a linear ultraviolet radiation absorbing polyether that comprises a covalently bound UV-chromophore and that comprises a backbone having glyceryl repeat units.

2. The polymer composition of claim 1 wherein the linear ultraviolet radiation absorbing polyether comprises a repeat unit selected from the group consisting of

where Y is the covalently bound UV-chromophore.

3. The polymer composition of claim 1 wherein the linear ultraviolet radiation absorbing polyether comprises a repeat unit

where Y is the covalently bound UV-chromophore.

4. The polymer composition of claim 1 wherein the linear ultraviolet radiation absorbing polyether comprises a repeat unit

where Y is the covalently bound UV-chromophore.

5. The polymer composition of claim 1 , comprising about 50% or more of said linear ultraviolet radiation absorbing polyether comprising the covalently bound UV-chromophore.

6. The polymer composition of claim 1 , comprising about 90% or more of said linear ultraviolet radiation absorbing polyether comprising the covalently bound UV-chromophore.

7. The polymer composition of claim 1 , comprising about 95% or more of said linear ultraviolet radiation absorbing polyether comprising the covalently bound UV-chromophore.

8. The polymer composition of claim 1 , wherein the linear ultraviolet radiation absorbing polyether is characterized as having the structure:

where R is a pendant group, Y represents the chemically bound UV-chromophore, X is a terminal group, and m and n are real numbers between 0 and 1.

9. The polymer composition of claim 8 , wherein m is 1 and n is 0.

10. The polymer composition of claim 8 , wherein X and R are independently selected from the group consisting of hydrogen, linear alkyl, alkenyl or alkynyl hydrocarbon chains, and linear siloxanes.

11. The polymer composition of claim 1 , wherein the linear ultraviolet radiation absorbing polyether is a reaction product of the ring opening polymerization of a monomer selected from a group consisting of ethylene oxide, propylene oxide, and a glycidyl ether.

12. The polymer composition of claim 11 , wherein the glycidyl ether is selected from the group consisting of n-butyl glycidyl ether and 2-ethylhexylglycidyl ether.

13. The polymer composition of claim 1 , wherein the UV-chromophore is selected from the group consisting of triazoles, camphors, dibenzoylmethanes, 4-aminobenzoic acid and alkane esters thereof, anthranilic acid and alkane esters thereof, salicylic acid and alkane esters thereof, hydroxycinnamic acid and alkane esters thereof, dihydroxy-, dicarboxy-, and hydroxycarboxybenzophenones and alkane ester or acid halide derivatives thereof, dihydroxy-, dicarboxy-, and hydroxycarboxychalcones and alkane ester or acid halide derivatives thereof, dihydroxy-, dicarboxy-, and hydroxycarboxycoumarins and alkane ester or acid halide derivatives thereof, benzalmalonate, benzimidazole derivatives, benzoxazole derivatives, 3-(3-(2H-benzo[d][1,2,3]triazol-2-yl)-5-(tert-butyl)-4-hydroxyphenyl), 6-octyl-2-(4-(4,6-di([1,1′-biphenyl ]-4-yl)-1,3,5-triazin-2-yl)-3-hydroxyphenoxy)propanoate and trioctyl 2,2′,2″-(((1,3,5-triazine-2,4,6-triyl) tris(3-hydroxybenzene-4,1-diyl))tris(oxy)) tripropanoate.

14. The polymer composition of claim 1 , wherein the UV-chromophore is selected from the group consisting of a benzotriazole and a triazine.

15. The polymer composition of claim 1 having a polydispersity index of about 1.5 or less.

16. The polymer composition of claim 1 having a polydispersity index of about 1.2 or less.

17. The polymer composition of claim 1 wherein said polymer composition is the reaction product of a polyglycerol ester and a UV-chromophore having a functional group suitable for covalent attachment to said polyglycerol ester.

18. The polymer composition of claim 1 wherein said polymer composition is substantially free of hyperbranched ultraviolet radiation absorbing polymers.

19. A composition comprising a cosmetically acceptable topical carrier and a polymer composition comprising a linear ultraviolet radiation absorbing polyether that comprises a chemically covalently bound UV-chromophore and that comprises a backbone having glyceryl repeat units.
