Abstract

The present invention relates to the use of polyolefins comprising atactic structural elements in floor coverings, in particular in rugs or artificial lawns. The polyolefins contain at most 30 mass % of ethylene, 70 to 100 mass % of or at most 30 mass % of propylene, and/or 70 to 100 mass % of or at most 25 mass % of 1-butene or other straight-chain 1-olefin. The total amount is 100 mass %. A triad distribution of propylene triad measured through <13>C-NMR method has 20 to 55 mass % of atactic structure, 40 to 80 mass % of isotactic structure and at most 30 mass % of syndiotaxy; and/or a triad distribution of 1-butene measured through <13>C-NMR method has 2 to 85 mass % of atactic structure and at most 20 mass % of syndiotaxy.

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...
