Abstract: An aqueous binder composition is provided that includes a carbohydrate and a crosslinking agent. In exemplary embodiments, the carbohydrate-based binder composition may also include a catalyst, a coupling agent, a process aid, a crosslinking density enhancer, an extender, a moisture resistant agent, a dedusting oil, a colorant, a corrosion inhibitor, a surfactant, a pH adjuster, and combinations thereof. The carbohydrate may be natural in origin and derived from renewable resources. Additionally, the carbohydrate polymer may have a dextrose equivalent (DE) number from 2 to 20. In at least one exemplary embodiment, the carbohydrate is a water-soluble polysaccharide such as dextrin or maltodextrin and the crosslinking agent is citric acid. Advantageously, the carbohydrates have a low viscosity and cure at moderate temperatures. The environmentally friendly, formaldehyde-free binder may be used in the formation of insulation materials and non-woven chopped strand mats. A method of making fibrous insulation products is also provided.

TL;DR: In this article, a carboxylic acid anhydride was used as a coupling agent for glass fibers to resinous plastics, including thermoplastics and thermosetting resins and the elastomeric materials.
Abstract: The silane coupling agents are prepared by reaction of the mercapto silane with a carboxylic acid anhydride whereby the mercapto group adds across the double bond of the anhydride. The compounds can be converted to the corresponding diacid by reaction with water, and are useful as coupling agents for bonding glass fibers to resinous plastics, including thermoplastics and thermosetting resins and the elastomeric materials.

TL;DR: The microparticles are composed of homogeneously distributed, intertwined macromolecules and polymers and can be formulated to provide a sustained release from the interior of the microparticle when placed in an appropriate aqueous medium, such as under physiological conditions as mentioned in this paper.
Abstract: Microparticles formed by mixing a macromolecule with a polymer at a pH near the isoelectric point of the macromolecule and incubating the mixture in the presence of an energy source for a predetermined length of time. The microparticles are composed of homogeneously distributed, intertwined macromolecule and polymer. Each microparticle allows aqueous fluids to enter and allows solubilized macromolecule and polymer to exit the microparticle and may be formulated to provide a sustained release of macromolecule and polymer from the interior of the microparticle when placed in an appropriate aqueous medium, such as under physiological conditions. Methods of production and methods of use for research, diagnostics and therapeutics are provided.
