Abstract
The present invention relates to a process for the preparation of composites from thermoplastic polymers and (semi)metal oxides, in particular silicon dioxide, wherein at least a part of the (semi)metal oxides is dispersed in the polymers in nanodispersed manner (nanocomposites). The invention relates to the composites obtainable by this process and their processing to give molded articles.
Claims17
A process for the preparation of composites from at least one thermoplastic polymer and at least one liquid polyalkyl(semi)metalate, comprising the following steps:
- i. introduction of at least one liquid polyalkyl(semi)metalate of silicon, titanium, zirconium or hafnium into a melt of at least one thermoplastic polymer and
- ii. condensation of the polyalkyl(semi)metalate in the polymer melt by adding at least one substance catalyzing the condensation forming a (semi)metal oxide phase distributed in the polymer in nanodispersed manner.
