Abstract

A linoleum composition including a dendritic substituent comprising (i) a polyfunctional core including a plurality of primary branches extending from the core and (ii) a plurality of dendritic branches extending from the plurality of primary branches, and each dendritic branch having an unsaturated functionality.

First claim

The invention claimed is:

1. A linoleum composition including a dendritic substituent comprising:
(i) a polyfunctional core including a plurality of primary branches extending from the core, the polyfunctional core derived from a polyglyceride of one or more C 16 to C 20 unsaturated fatty acids; and
(ii) a plurality of first dendritic branches extending from the plurality of primary branches, and
(iii) a plurality of second dendritic branches pendant from the first dendritic branches, each secondary dendritic branch having an unsaturated functionality;
wherein the number of second dendritic branches is greater than the number of first dendritic branches.

2. The linoleum composition of claim 1 , wherein the polyglyceride comprises a triglyceride.

3. The linoleum composition of claim 1 , wherein the one or more C 16 to C 20 unsaturated fatty acids comprise at least one C 18 fatty acid.

4. The linoleum composition of claim 1 , wherein the polyglyceride is derived from linseed oil and comprises derivatives of linoleic, oleic and alpha-linoleic acid.

5. The linoleum composition of claim 1 , wherein the first dendritic branch is derived from at least one second unsaturated fatty acid selected from a C16 to C20 unsaturated fatty acid.

6. The linoleum composition of claim 5 , wherein the at least one second unsaturated fatty acid is a C 18 unsaturated fatty acid.

7. The linoleum composition of claim 6 , wherein the at least one second unsaturated fatty acid is linoleic acid.

8. The linoleum composition of claim 1 , wherein the first dendritic branch is derived from at least one third unsaturated fatty acid and having an unsaturated functionality, and the second dendritic branch being derived from at least one fourth unsaturated fatty acid and having an unsaturated functionality.

9. The linoleum composition of claim 8 , wherein at least one or both of the third and fourth unsaturated fatty acids is a C16 to C20 unsaturated fatty acid.

10. The linoleum composition of claim 9 , wherein at least one or both of the third and fourth unsaturated fatty acids is linoleic acid.

11. The linoleum composition of claim 1 , wherein the second dendritic branch has a hydroxyl functionality.

12. The linoleum composition of claim 1 , wherein each dendritic branch has a tertiary substituent derived from reaction, with a hydroxyl functionality on the dendritic branch, of a capping component selected from at least one of the group consisting of an acid, an acid anhydride, an acid chloride, an isocyanate and a silicon-containing material.

13. The linoleum composition of claim 1 , wherein there are 2 to 4 of the first dendritic branches per primary branch of the polyfunctional core.

14. The linoleum composition of claim 13 , wherein there are 2 to 4 of the second dendritic branches per first dendritic branch.

15. A linoleum composition comprising a dendritic substituent having the formula:

wherein
X=—C(O)—(CH 2 ) 7 —CH(OH)—CH(OY)—CH 2 —CH(OH)—CH(OY)—(CH 2 ) 4 —CH 3
Y=—C(O)—(CH 2 ) 7 —CH(OH)—CH(OZ)—CH 2 —CH(OH)—CH(OZ)—(CH 2 ) 4 —CH 3 ; and
Z=—C(O)—(CH 2 ) 7 —CH═CH—CH 2 —CH═CH—(CH 2 ) 4 —CH 3 ;
wherein R is derived from a polyglyceride of one or more C 16 to C 20 unsaturated fatty acids.

16. A linoleum composition comprising a dendritic substituent having the formula:

wherein
X=—C(O)—(CH 2 ) 7 —CH(OY)—CH(OY)—CH 2 —CH(OY)—CH(OY)—(CH 2 ) 4 —CH 3
Y=—C(O)—(CH 2 ) 7 —CH(OZ)—CH(OZ)—CH 2 —CH(OZ)—CH(OZ)—(CH 2 ) 4 —CH 3 ; and
Z=—C(O)—(CH 2 ) 7 —CH═CH—CH 2 —CH═CH—(CH 2 ) 4 —CH 3 ;
wherein R is derived from a polyglyceride of one or more C 16 to C 20 unsaturated fatty acids.

17. The linoleum composition of claim 1 , wherein each dendritic branch is cross-linked to a further dendritic branch by a cross-linking substituent derived from reaction, with a hydroxyl functionality on the cross-linked dendritic branches, of a cross-linking component selected from at least one of the group consisting of a melamine, an isocyanate and a silicon-containing material.
