Herein disclosed is a composition containing from about 5 weight parts to about 50 weight parts of a branched polylactic acid; from about 50 weight parts to about 95 weight parts of water; and from about 0.1 weight parts to about 1 weight part of a first surfactant. The composition can be coated onto a substrate containing paper or paperboard and having a first surface and a second surface, to form a paper product having oil, grease, and moisture resistance.

A crosslinked lactic acid polymer composition containing (i) a macromer comprising (i-a) a flexible segment produced by the condensation of two or more compounds selected from the group consisting of lactones, furans, epoxies, isocyanates, anhydrides, dianhydrides, alcohols, diols, triols, carboxylic acids, dicarboxylic acids, tricarboxylic acids, esters, diesters, triesters, ethers, diethers, and triethers; and (ii) a lactic acid polymer produced by the condensation of a lactic acid monomer ordimer selected from the group consisting of D-lactic acid, L-lactic acid, D,L-lactic acid, L,L-lactide, D,D-lactide, and D,L-laclide; wherein the macromer and the lactic acid polymer contain carbon-carbon single-bond crosslinks. The macromer may further contain (i-b) a lactic acid segment produced by the condensation of a lactic acid monomer or dimer selected from the group consisting of D-lactic acid, L-lactic acid, D,L-lactic acid, L,L-lactide, D,D- lactide, and D,L-lactide with a polytunctional monomer selected from the group consisting of dianhydrides, diols, triols, dicarboxylic acids, and tricarboxylic acids. Also, methods of producing the polymer composition.

Lactic acid based compositions with enhanced properties

A process for producing alpha-amylase resistant starch comprises extruding a feed starch at a temperature in the range of about 60-220&#xb0; C., thereby producing a product alpha-amylase resistant starch. The feed starch can be in the form of an aqueous slurry or paste that has a dry solids concentration of at least about 50% by weight. The process optionally can include the additional step of heating the product starch to a temperature of at least about 90&#xb0; C. in the presence of moisture, to increase further the alpha-amylase resistance of the product.
