Described herein are compositions comprising a vinyl acrylic copolymer derived in the presence of maltodextrin. In some examples, the compositions comprise a copolymer derived from: vinyl acetate; an acrylate monomer having a Tg of 30 C. or less; a carboxylic acid, a carboxylic acid anhydride, or a combination thereof; and an organosilane; in the presence of maltodextrin. The copolymer can be provided as an aqueous dispersion. In some examples, the aqueous dispersion can have an overall solids content of from 40% to 75%. Also disclosed herein are carpet tiles having a surface coated with the adhesive formulations disclosed herein. In some examples, the carpet tile with the adhesive formulation applied thereto can pass the British spill test. Also disclosed herein are methods of making the compositions disclosed herein.

The present invention relates to a molecularly imprinted polymer for binding glycans, wherein the molecularly imprinted polymer is obtainable by providing a saccharide template such as a glycan; providing at least two functional monomers capable of cooperatively; interacting with the template; providing a crosslinking monomer; polymerizing the monomers optionally dissolved in a solvent, in presence of the saccharide template; and removing the template from the formed polymer. The invention is also related to a method for their production and use of the molecularly imprinted polymer.

The present disclosure discloses a thermosetting starch adhesive for a wood-based panel and a preparation method therefor, and belongs to the technical field of preparation of adhesives. In the present disclosure, starch is used as a main raw material, and after acid hydrolysis thereof, a semi-continuous seed emulsion polymerization method is adopted to improve control of monomer polymerization stability. After grafting is completed, a cross-linking monomer with polymerizable double bonds and condensable methylol functional groups is added for copolymerization. The cross-linking monomer is also added in a semi-continuous manner. After the cross-linking reaction is completed, the reaction mixture is gelatinized and incubated, and finally a thermosetting adhesive which can be used for bonding of hot-pressed wood-based panels is obtained. The adhesive of the present disclosure has the properties of two-step cross-linking and high-temperature rapid cross-linking curing, good film formation, good heat resistance, and strong cohesion. With a hot-pressing process in an appropriate coating manner, appropriate temperature and pressure, the resultant wood-based panels have all their properties superior over those of Class II wood-based panels, and they can be widely used in decoration of hot-pressed woods, and bonding of wood-based panels and plywoods.
