    Abstract: Disclosed is a composition comprising at least one interpolymer dispersed within an aqueous medium, the interpolymer comprising at least one unsaturated monomer and at least one selected from the group consisting of at least one conjugated acid, at least one mono-ester of a conjugated acid, and mixtures thereof, and, optionally, at least one surfactant configured to stabilize the interpolymer within the aqueous medium. The conjugated acid may be derived from a naturally-occurring oil, such as tung oil. There is also provided a method for preparing a composition, comprising forming an interpolymer comprising the at least one unsaturated monomer and the at least one selected from the group consisting of at least one conjugated acid, at least one mono-ester of a conjugated acid, and mixtures thereof. There is still further provided a pressure sensitive adhesive comprising the composition prepared according to the disclosed method.

    Abstract: A method for making a water-based adhesive composition is disclosed. The method comprises dispersing at least one unsaturated monomer and at least one surfactant in an aqueous medium to form an emulsified mixture. The method further comprises introducing at least one initiator to the emulsified mixture, thereby polymerizing the at least one unsaturated monomer and forming an emulsion polymer. The method still further comprises introducing at least one polyol ester of a conjugated acid to the emulsion polymer upon completion of polymerization of the at least one unsaturated monomer. The conjugated acid may be derived from a naturally-occurring dry oil, such as tung oil. There is still further provided a pressure sensitive adhesive comprising the composition prepared according to the disclosed method.

    Abstract: An adhesive composition is provided. The adhesive composition comprises the following components: (a) a polyacid polymer aqueous dispersion, wherein the polyacid polymer contains 50%˜100% by weight of one or more ethylenically unsaturated mono- or dicarboxylic acid/anhydrides; (b) a hydroxyl group-containing acrylic copolymer emulsion, wherein the hydroxyl group-containing acrylic copolymer is obtained from polymerizing a monomer mixture which contains 0.1-10% hydroxyl group-containing monomer, 0.1% to 20% weight unsaturated carboxylic acid and 30%-90% acrylic monomer, wherein the solid weight ratio of the above components (a) and (b) is 0.1:100 to 10:100, based on the solids of the components (a) and (b).

    Abstract: A solventless adhesive is disclosed, the adhesive comprising an isocyanate component comprising at least one isocyanate prepolymer that is the reaction product of reactants comprising at least one isocyanate, at least one polyol, and a branched alkane diol, and a polyol component comprising at least one polyol and a branched alkane diol. The branched alkane diol can comprise a single side alkyl chain, such as 3-methyl-1,5-pentanediol, 2-methyl-1,3-propanediol, and combinations thereof. Further, a method for forming a laminate is disclosed, the method comprising forming a solventless adhesive composition comprising a branched alkane diol, applying a layer of the adhesive composition to a surface of a film, bringing the layer into contact with a surface of another film to form a laminate, and curing the adhesive composition. Still further, a laminate formed by the method is disclosed.
