The present invention provides cyclic dimers of alpha acids and polymers derived therefrom. Also provided are processes for preparing and methods of using the cyclic dimers and the polymers derived from the cyclic dimers.

Heteroatom containing cyclic dimers

Processes for preparing heteroatom containing cyclic dimers that result in increased production efficiency and reduced waste production.

Processes for preparing heteroatom containing cyclic dimers

Hydrocarbyl terminated polyester compounds comprising sulfur-containing repeat units that are useful as plastic modifiers, polymer blend compositions comprising the hydrocarbyl terminated polyester compounds, methods for modifying the performance properties of polymers, and methods for preparing the hydrocarbyl terminated polyester compounds.

Plastic modifiers

Formulations comprising hydroxy methionine analog and having low levels of sulfate ions and bisulfate salts, processes for preparing the formulations, compositions comprising the formulations, and methods of using the formulations.

Hydroxy methionine analog formulations suitable for specialty chemical applications

The invention relates to matrix and layer compositions comprising a first polymer. The matrix and layer compositions are useful in the delivery of bioactives. In particular, the matrices and layers may have advantageous properties including mechanical properties and protection of bioactives and may also provide for pH-dependent release of a bioactive.

Matrix and layer compositions for protection of bioactives

The present invention provides sulfur- or selenium-containing compounds comprising hydrophobic moieties and ethoxylated ester or ethoxylated amide moieties such that the compounds have surfactant properties. Also provided are methods for using the disclosed compounds or mixtures thereof in a variety of applications.

Ethoxylated surfactants

The invention relates to functionalized polymers including homopolymers and copolymers and their uses in industrial applications and in agricultural applications. In particular, the homopolymers and copolymers may be, for example, used in polymer blends, used as nutritives and in feed compositions, and used in combination with a pharmaceutical or nutritive.
