Abstract
Disclosed herein are aqueous latex compositions comprising polysaccharide particles and a polymer dispersion or polymer emulsion. In one embodiment the polysaccharide particles comprise poly alpha-1,3-glucan. Also disclosed are an adhesive, film, coating, or binder comprising the latex composition in a dry form, as well as articles comprising the adhesive, film, coating, or binder.
Claims18
An aqueous latex composition comprising polysaccharide particles, and a polymer dispersion or polymer emulsion;
- wherein the polysaccharide particles comprise at least one polysaccharide comprising:
- (i) a poly alpha-1,3-glucan ester compound represented by Structure 1:
- wherein
- (A) n is at least 6,
- (B) each R is independently an —H or a first group comprising —CO—Cx—COOH, wherein the —Cx— portion of said first group comprises a chain of 2 to 18 carbon atoms, and
- (C) the poly alpha-1,3-glucan ester compound represented by Structure 1 has a degree of substitution with the first group of 0.001 to 3.0;
- or
- (ii) a poly alpha-1,3-glucan ester compound represented by Structure 2:
- wherein
- (A) n is at least 6,
- (B) each R is independently an —H or an acyl group, and
- (C) the poly alpha-1,3-glucan ester compound represented by Structure 2 has a degree of substitution with the acyl group of 0.001 to 3.0.
