Problems solved by technology

[0008] However, even with the use of surface-modified or unmodified fillers mixed into polyolefin resin matrices, problems with highly uniform dispersions are still encountered
Furthermore, debonding is not sufficiently prevented to achieve the material's theoretical potential
Furthermore, the prior art suffers from serious problems when the final polymeric composition is subjected to mechanical loads and / or deformations, leading to debonding and cavitation at the particle surface, causing stress whitening, and eventual cracking of the composition

Abstract

The present invention relates to a polyolefin composition comprising a polyolefin base resin comprising an olefin homo- or copolymer (A) having hydrolysable silicon-containing groups, and an inorganic mineral filler (B) containing on its surface silanol groups or precursors thereof.

Description

technical field [0001] The present invention relates to polyolefin compositions with improved mechanical strength, especially toughness and improved impact strength and heat resistance. In particular, the present invention relates to a polyolefin composition in which a filler containing a silicon compound is firmly embedded in the polyolefin. The invention also relates to articles made from said polyolefin composition, and the use of said polyolefin composition for the production of articles. Background technique [0002] Due to their chemical and heat resistance as well as their mechanical strength, polyolefin compositions are used in a variety of fields of application, for example in molding, film or other fields of application. [0003] For demanding applications, such as at very low temperatures, or for heavy packaging, polyolefins used for these purposes often lack mechanical strength and heat resistance. Therefore, non-polymeric reinforcing materials such as mineral ...
