METHOD OF PREPARING POLYOLEFIN NANOCOMPOSITES Russian patent published in 2009 - IPC C08G81/00 B32B3/00 

FIELD: chemistry.

SUBSTANCE: method of preparing polyolefin nanocomposite includes mixing in melt mixture of polyolefin, filling agent and non-ionogenic surface-active substance. Claimed is method of preparing polyolefin nanocomposite, which includes mixing in melt mixture of polyolefin, filling agent representing natural or synthetic phyllosilicate or their mixture, or layered hydrocarbonate and non-ionogenic surface-active substance, such as sorbitan ester, dimethylsiloxane-ethyleneoxide or poly(methylmethacrylate)-poly(oxyethylene) blockcopolymer. Also claimed are versions of obtained by claimed method polyolefin nanocomposite and products from it.

EFFECT: nanocomposites with improved properties and possibility to use natural filling agent which is not modified before application.
