Abstract

Polyester compositions are disclosed herein, as well as methods of making and using such polyesters. In some embodiments, the polyesters are formed from monomers derived from natural oils.

Claims (33)

1 - 31 . (canceled)

32 . A block copolymer, which comprises a first block and a second block, wherein the first block comprises a polyester polymer comprising constitutional units formed from a reaction mixture comprising one of more monomers of Formula (Ia):

and one or more monomers for Formula (Ib):

wherein:

R 1 is —OH or —OR 3 ;

R 2 is —O—(C 1-6 alkyl);

R 3 is C 1-6 alkyl or C 1-6 oxyalkyl;

X 1 is C 4-10 alkylene;

R 11 is —OH or —OR′ 3 ;

R 12 is —O—(C 1-6 alkyl);

R 13 is C 1-6 alkyl or C 1-6 oxyalkyl; and

X 11 is C 4-10 alkylene.

33 . The block copolymer of claim 32 , where the second block comprises a poly(alkylene oxide).

34 . The block copolymer of claim 33 , wherein the poly(alkylene oxide) is selected from the group consisting of poly(ethylene oxide), poly(1,2-propylene oxide), and poly(1,3-propylene oxide).

35 . The block copolymer of claim 32 , wherein the second block comprises polycaprolactone.

36 . The block copolymer of claim 32 , wherein the second block comprises a polycarbamate.

37 . The block copolymer of claim 32 , wherein the second block comprises a polyester.

38 . The block copolymer of claim 32 , wherein the second block comprises a polyamide.

39 . The block copolymer of claim 32 , wherein the second block comprises a polyamide ester.

40 . The block copolymer of claim 32 , wherein R 1 is —OH.

41 . The block copolymer of claim 32 , wherein R 1 is —OR 3 .

42 . The block copolymer of claim 41 , wherein R 3 is methyl.

43 . The block copolymer of claim 32 , wherein R 2 is methyloxy, ethyloxy, or n-propyloxy.

44 . The block copolymer of claim 32 , wherein X 1 is —(CH 2 ) 7 —.

45 . The block copolymer of claim 32 , wherein R 11 is —OH.

46 . The block copolymer of claim 32 , wherein R 11 is —OR 13 .

47 . The block copolymer of claim 46 , wherein R 13 is methyl, ethyl, or isopropyl.

48 . The block copolymer of claim 32 , wherein R 13 is methyl.

49 . The block copolymer of claim 43 , wherein R 12 is methyloxy, ethyloxy, or n-propyloxy.

50 . The block copolymer of claim 43 , wherein X 11 is —(CH 2 ) 7 —.

51 . The block copolymer of claim 32 , wherein the reaction mixture comprises one or more diols.

52 . The block copolymer of claim 32 , wherein the reaction mixture further comprises one or more diacids, or esters thereof.

53 . The block copolymer of claim 32 , wherein the reaction mixture further comprises one or more hydroxy acids, or esters thereof.
