Abstract
The instant invention discloses a composition, preferably a nanocomposite material, comprising (a) a synthetic polymer, (b) a filler such as for example a natural or synthetic phyllosilicate or a mixture of such phyllosilicates, preferably in nanoparticles, and (c) as dispersing agent a polymer based on a long chain alkyl meth(acryte).
Claims22
A composition comprising
- a) a synthetic polymer,
- b) a filler, and
- c) as dispersing agent a polymer based on a long chain alkyl meth(acrylate).
A process for the preparation of a synthetic polymer nanocomposite material which comprises melt mixing a mixture of a) a synthetic polymer, b) a filler, and c) as dispersing agent a polymer based on a long chain alkyl meth(acrylate).
Use of a polymer based on a long chain alkyl meth(acrylate) to intercalate and exfoliate a filler and disperse the filler in a synthetic polymer matrix to form a nanocomposite material.
