POLYMERS AND METHODS OF MAKING THE SAME

摘要

Various embodiments disclosed relate to polymers and methods of making the same. In various embodiments, the present invention provides a method of forming a polymer including subjecting a composition including a carboxylic acid having the structure (Rf—O)z1—Ra to conditions sufficient to form a polymer having the structure Reg—[O—Ra(O—Rb)z1-2—O—C(O)—R′(O—Rd)z2-1—C(O)]n—O—Ra(O—Rb)z1-2—O—Reg or a salt or ester thereof, wherein Ra, R′ Rb, Rd, Rf, Reg, z1, z2, and n are as defined herein. In various embodiments, the polymer is a tackifier, a viscosifier, or a combination thereof.

1. A method of forming a polymer, the method comprising:
subjecting a composition comprising a carboxylic acid having the structure (Rf—O)z1—Ra to conditions sufficient to form a polymer having the structure Reg—[O—Ra(O—Rb)z1-2—O—C(O)—R′(O—Rd)z2-1—C(O)]n—O—Ra(O—Rb)z1-2—O—Reg or a salt or ester thereof, wherein
Ra is a substituted or unsubstituted (C1-C50)hydrocarbyl having a valency of z1 and interrupted or terminated by 0, 1, 2, or 3 groups independently chosen from —O—, —S—, substituted or unsubstituted —NH—, and —(O—(C2-C3)alkylene)y1- wherein y1 is about 1 to about 10,000 and wherein the (C2-C3)alkylene is substituted or unsubstituted,at each occurrence, R′ is independently a substituted or unsubstituted (C1-C50)hydrocarbyl having a valency of z2+1 interrupted or terminated by 0, 1, 2, or 3 groups independently chosen from —O—, —S—, substituted or unsubstituted —NH—, and —(O—(C2-C3)alkylene)y2- wherein y2 is about 1 to about 10,000 and wherein the (C2-C3)alkylene is substituted or unsubstitutedat each occurrence, Rb is independently chosen from —H, —C(O)—R′(O—Rd)z2-1—C(O)—[O—Ra(O—Rc)z2-1—O—C(O)—R′(O—Rd)z2-1—C(O)]n1—OH, and —C(O)—R′(O—Rd)z2-1—C(O)—[O—Ra(O—Rc)z1-2—O—C(O)—R′(O—Rd)z2-1—C(O)]n1—O—Ra(O—Rc)z1-2—O—Reg, wherein at each occurrence, n1 is independently about 0 to about 100,000,at each occurrence, Rc is independently chosen from —H, —C(O)—R′(O—Rd)z2-1—C(O)—[O—Ra(O—Rb)z1-2—O—C(O)—R′(O—Rd)z2-1—C(O)]n2—OH, and —C(O)—R′(O—Rd)z2-1—C(O)—[O—Ra(O—Rb)z1-2—O—C(O)—R′(O—Rd)z2-1—C(O)]n2—O—Ra(O—Rb)z2-1—O—Reg, wherein at each occurrence, n2 is independently about 0 to about 100,000,at each occurrence, Rd is independently chosen from —H, —C(O)—[O—Ra(Rb)z1-2—O—C(O)—R′(O—Re)z2-1—C(O)]n3—OH, and —C(O)—[O—Ra(O—Rb)z1-2—O—C(O)—R′(O—Re)z2-1—C(O)]n3—O—Ra(O—Rb)z2-1—O—Reg, wherein at each occurrence, n3 is independently about 0 to about 100,000,at each occurrence, Re is independently chosen from —H, —C(O)—[O—Ra(O—Rb)z1-2—O—C(O)—R′(O—Rd)z2-1—C(O)]n4—OH, and —C(O)—[O—Ra(O—Rb)z1-2—O—C(O)—R′(O—Rd)z2-1—C(O)]n4—O—Ra(Rb)z1-2—O—Reg, wherein at each occurrence, n4 is independently about 0 to about 100,000,at each occurrence, Rf is independently chosen from (HO—C(O))z2—R′—C(O)— and H—, wherein at least one Rf in each molecule containing Rf is (HO—C(O))z2—R′—C(O)—,at each occurrence, Reg is independently chosen from HO—C(O)—R′(O—Rd)z2-1—C(O)— and H—,z1 is about 2 to about 100,z2 is about 1 to about 100, andn is about 1 to about 100,000.
