Abstract: A nano-particle composition including a poly (alkenylbenzene) core and a poly (conjugated diene) or a poly(alkylene) surface layer is provided. The nano-particles have a mean average diameter less than about 100nm. The nano-particles can be modified via, for example, hydrogenation or functionalization. The nano-particles can advantageously be incorporated into rubbers, elastomers, and thermoplastics.

Abstract: The present invention discloses a product obtainable by reacting a nano-scaled filler with a compound of the formula (I): AD-L-RG, wherein AD is an additive selected from the group of radical scavengers, hydroperoxide decomposers, UV-absorbers, light stabilizers, flame retardants or photoinitiators, L is a spacer, RG is a reactive group, and the nano-scaled filler can be of unmodified or organophilically modified character. These products are for example useful as stabilizers and/or compatibilizers in organic materials, or as photoinitiators in pre-polymeric or pre-crosslinking formulations.

Abstract: An optical nanocomposite material has a nanoparticulate filler dispersed in a host plastic material. According to the method of making the nanocomposite material, a predetermined temperature sensitive optical vector, such as refractive index, of the plastic host material and nanoparticulate filler are directionally opposed resulting in a nanocomposite material having significantly improved stability of the refractive index with respect to temperature.
