Abstract
Disclosed are polyesters, particularly poly(trimethylene terephthalate), comprising fluorovinylether functionalized aromatic repeat units, and methods to make the polyester polymers. The polymers are useful for imparting soil resistance to polyesters, particularly in the form of fibers, fabrics, and carpets.
Claims37
A polymer comprising a fluorovinyl ether functionalized aromatic repeat unit represented by the structure (I)
- wherein,
- Ar represents a benzene or naphthalene radical;
- each R is independently H, C1-C10 alkyl, C5-C15 aryl, C6-C20 arylalkyl;
- OH, or a radical represented by the structure (II)
- with the proviso that only one R can be OH or the radical represented by the structure (II);
- R1 is a C2-C4 alkylene radical which can be branched or unbranched,
- X is O or CF2;
- Z is H, Cl, or Br;
- a=0 or 1;
- and,
- Q represents the structure (Ia)
- wherein q=0-10;
- Y is O or CF2;
- Rf1 is (CF2)n, wherein n is 0-10;
- and,
- Rf2 is (CF2)p, wherein p is 0-10, with the proviso that when p is 0, Y is CF2.
A process, comprising combining a fluorovinyl ether functionalized aromatic diester or diacid with a C2-C4 alkylene glycol, branched or unbranched, and a catalyst to form a reaction mixture;
- and stirring the reaction mixture to form a polymer comprising repeat units having the structure (I), wherein the fluorovinyl ether functionalized aromatic diester or diacid is represented by the structure (III),
- wherein,
- Ar represents a benzene or naphthalene radical;
- each R is independently H, C1-C10 alkyl, C5-C15 aryl, C6-C20 arylalkyl;
- OH, or a radical represented by the structure (II)
- with the proviso that only one R can be OH or the radical represented by the structure (II);
- R2 is H or C1-C10 alkyl;
- X is O or CF2;
- Z is H, Cl, or Br;
- a=0 or 1;
- and,
- Q represents the structure (Ia)
- wherein q=0-10;
- Y is O or CF2;
- Rf1 is (CF2)n, wherein n is 0-10;
- and,
- Rf2 is (CF2)p, wherein p is 0-10, with the proviso that when p is 0, Y is CF2.
