Abstract

Claims (29)

1. A composition comprising a farnesene interpolymer, wherein the farnesene interpolymer has formula (X′):

wherein n is from 1 to about 100,000; m is from 1 to about 100,000; X has one or more of formulae (I′)-(VIII′):

and

Y has formula (IX′):

wherein R 1 has formula (XI):

R 2 has formula (XII):

R 3 has formula (XIII):

and

R 4 has formula (XIV):

wherein each of R 5 , R 6 , R 7 and R 8 is independently H, alkyl, cycloalkyl, aryl, cycloalkenyl, alkynyl, heterocyclyl, alkoxy, aryloxy, carboxy, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, acyloxy, nitrile or halo, and wherein a mole percent ratio of X to Y is from about 1:4 to about 100:1.

2. The composition of claim 1 , wherein the farnesene interpolymer has a weight-average molecular weight greater than about 60,000 daltons.

3. The composition of claim 1 , wherein the farnesene interpolymer has a T g less than about −60° C.

4. The composition of claim 1 , wherein formula (II′) is in an amount of from about 5 wt. % to about 99 wt. %, based on a total weight of the farnesene interpolymer.

5. The composition of claim 1 further comprising an additive.

6. The composition of claim 5 , wherein the additive is selected from the group consisting of tackifiers, plasticizers, oils, waxes, antioxidants, UV stabilizers, colorants or pigments, fillers, flow aids, coupling agents, crosslinking agents, surfactants, solvents and combinations thereof.

7. The composition of claim 1 , wherein the farnesene interpolymer is a random farnesene interpolymer.

8. The composition of claim 1 , wherein the farnesene interpolymer is a block farnesene interpolymer.

9. The composition of claim 8 , wherein the block farnesene interpolymer according to formula X′ comprises one block of one or more X and two blocks each of one or more Y and wherein the one block of one or more X is between the two blocks each of one or more Y.

10. The composition of claim 9 , wherein R 5 is aryl; and each of R 6 , R 7 and R 8 is H.

11. The composition of claim 10 , wherein the aryl is phenyl.

12. The composition of claim 1 , wherein formula (III′) is in an amount of at least about 70 wt. %, based on a total weight of the farnesene interpolymer.

13. The composition of claim 1 , wherein formula (I′) is in an amount of at most about 80 wt. %, based on a total weight of the farnesene interpolymer.

14. An article comprising a substrate coated with the composition of claim 1 .

15. The article of claim 14 , wherein the article is a paper product, packaging material, laminated wood panel, kitchen countertop, vehicle, label, disposable diaper, hospital pad, feminine sanitary napkin, surgical drape, tape, case, carton, tray, medical device or bandage.

16. A composition comprising a farnesene interpolymer, wherein the farnesene interpolymer is prepared by copolymerizing a farnesene with a vinyl monomer in the presence of a catalyst, wherein a mole percent ratio of the farnesene to the vinyl monomer is from about 1:4 to about 100:1, and wherein the vinyl monomer does not comprise an isoprene.

17. The composition of claim 16 , wherein the farnesene is an α-farnesene, β-farnesene or a combination thereof.

18. The composition of claim 16 , wherein the vinyl monomer is styrene.

19. The composition of claim 16 , wherein the farnesene is derived from a simple sugar.

20. An article comprising a substrate coated with the composition of claim 16 .
