Abstract

The disclosure relates to benzyl α-(1→3)-glucan, compositions comprising benzyl α-(1→3)-glucan, and blends comprising benzyl α-(1→3)-glucan and one or more polymers. Also disclosed are fibers comprising benzyl α-(1→3)-glucan, and articles comprising such fibers, including articles such as a carpet, a textile, a fabric, yarn, or apparel.

Claims (14)

1 . Benzyl α-(1→3-)-glucan.

2 . The benzyl α-(1→3)-glucan of claim 1 , wherein the benzyl α-(1→3)-glucan has a degree of substitution in the range of from 0.01 to 3.0.

3 . The benzyl α-(1→3)-glucan of claim 1 , wherein the benzyl α-(1→3)-glucan has a number average molecular weight in the range of from 10,000 to about 2,000,000 daltons.

4 . The benzyl α-(1→3)-glucan of claim 1 , wherein the glucose repeat units comprise greater than or equal to 50% α-(1→3)-glucoside linkages.

5 . The benzyl α-(1→3)-glucan of claim 1 , wherein the benzyl group is substituted with one or more of a halogen, a cyano, an ester, an amide, an ether group, a C 1 to C 6 alkyl group, an aryl group, a C 2 to C 6 alkene group, a C 2 to C 6 alkyne group, or a combination thereof.

6 . A composition comprising benzyl α-(1→3)-glucan.

7 . The composition of claim 6 , wherein the composition further comprises a solvent.

8 . The composition of claim 7 , wherein the solvent is dimethyl sulfoxide, dimethyl acetamide, dimethyl formamide, pyridine, 1-methyl-2-pyrrolidinone, or a combination thereof.

9 . A blend comprising benzyl α-(1→3)-glucan and one or more polymers.

10 . The blend of claim 9 , wherein the one or more polymers are polyaramid, polyacrylonitrile, cellulose, or a combination thereof.

11 . A fiber comprising benzyl α-(1→3-)-glucan.

12 . The fiber of claim 11 , wherein the fiber is a blend of benzyl α-(1→3)-glucan with one or more polymers, and wherein the one or more polymers are polyaramid, polyacrylonitrile, cellulose, or a combination thereof.

13 . An article comprising the fiber of claim 11 .

14 . The article of claim 13 , wherein the article is a carpet, a textile, a fabric, yarn, or apparel.
