Patent ID: 7879938

Claim:
A composition comprising a nanocomposite and optional additives, wherein: A) said nanocomposite comprises: a) 20 to 99.9% by wt. of an organic polymer as a matrix and b) 0.1 to 80% by wt. of inorganic particles as filler, wherein: i) the sum of said organic polymer and said inorganic particles amounts to 100% by wt. of said nanocomposite; ii) said inorganic particles are aggregates of globular primary particles with a size in the range of 0.5 nm to less than 100 nm; iii) the volume-weighted median value d 50 of said inorganic particles is between 0.05 μm and 0.5 μm, as determined by means of static light scattering; and iv) said inorganic particles comprise at least three types of functional groups of varying reactivity; B) said optional additives comprise 0 to 100 parts by weight of said composition, wherein the content of the additives relates to the sum of a) and b), calculated as 100 parts by weight.
