Abstract

The invention relates to filled polyolefin compositions having improved mechanical and surface properties and to a process for preparing them. The invention provides a composition of polyolefin reinforced with filler(s), impact modifier(s) and a fibrous sub micron structured material, the composition having improved surface properties, mechanical properties and crystallinity, the composition comprising atleast two polyolefins, one polyolefin having high melt flow index (MFI) and another polyolefin having low melt flow index. The invention also provides a process for preparing a filled polyolefin composition by melt mixing a mixture of polyolefins, impact modifier(s), a fibrous sub micron structured material and filler(s), the mixture comprising at least two polyolefins, one polyolefin having a higher MFI than the other.
