This invention relates to a curable casting compound for the manufacture of molded plastics, comprising a casting compound having a binder composition and a filler composition, wherein the filler composition has at least a first portion of an inorganic filler and a second portion of an organic filler, wherein the second portion of organic filler comprises comminuted nutshells—as a nutshell portion, in particular granular nutshells, having a percentage by weight of 1% by wt. to 100% by wt. of the filler composition.

Embodiments of this invention relate to adhesives, and more particularly to biomimetic heteropolymer adhesive compositions. Certain embodiments relate to biomimetic terpolymer adhesive compositions including dopamine methacrylamide, 3,4-dihydroxyphenylalanine, or 3,4-dihydroxystyrene, mimicking moieties found in marine mussel adhesive proteins. In some embodiments, elastic moduli of the adhesives are preferably selected to match the elastic moduli of the substrates to minimize stress concentrations, to increase the ductility of the adhesive-substrate system, or both.

The invention provides (meth)acrylic oligomers prepared from C1-C20 alkyl and C5-C20 cycloalkyl (meth)acrylates, wherein said oligomers have a Mn of about 300 g/mole to about 3,000 g/mole; a Mw of about 700 g/mole to about 6,000 g/mole; a Mz of about 900 g/mole to about 10,000 g/mole. The oligomers may have a Yellowness Index, according to ASTM E313 of less than 2. The oligomers of the invention are useful as tackifiers in adhesive compositions, but also are believed to be useful also in general polymer modification as plasticizers, leveling agents, viscosity reducers (i.e., rheology modifiers), and for increasing solids content in solvent-borne applications of all types with little detrimental impact on viscosity. The invention also provides adhesive compositions and laminate articles coated on at least one side with the adhesive compositions of the invention.
