Abstract

The present invention relates to the use of polyolefins having atactic structural elements in floor coverings, in particular in carpets or artificial lawns.

Description

technical field [0001] The invention relates to the use of polyolefins having atactic structural units for floor coverings, in particular carpets or artificial turf. Background technique [0002] The use of amorphous olefin polymers for the production of carpets and / or rug tiles has long been known. For example, US 3,928,281 describes the use of atactic polypropylene and urethane prepolymer and inorganic filler material composition for making carpet back coating. The use of isocyanate-containing compounds in the carpet making process is not conducive to the recycling of such carpets and is undesirable for toxicity reasons. Furthermore, the atactic polypropylene used does not have the material properties required for the simultaneous embedding of tufts and filaments, eg no defined polymer structure, and especially low coat weights cannot be achieved. [0003] US 3,551,231 discloses the use of hot melt adhesives (Schmelzklebstoff) for the back coating of carpets. In particu...
