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

Use of polyolefins having isotactic structural elements in flooring materials

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

Use of polyolefins having atactic structural elements in floor coverings

A one-layer or multilayer sheet having good layer adhesion and good transparency is produced using a polyolefin which contains the following monomer units:

Use of a highly viscous largely amorphous polyolefin for the production of a film

Artificial turf stock materials useful for artificial turf stock backfixing, including: a hotmelt made of: a) from 5% to 100% by weight of at least one amorphous poly-&#x3b1;-olefin, b) from 0% to 100% by weight of at least one modified amorphous poly-&#x3b1;-olefin, c) from 0% to 40% by weight of at least one resin, d) from 5% to 15% by weight of at least one modified crystalline polypropylene, e) from 0% to 20% by weight of at least one crystalline polyolefin, f) from 0% to 80% by weight of fillers or pigments, g) from 0% to 20% by weight of at least one flame retardant, and h) from 0% to 20% by weight of at least one wax, where ribbon yarn of polyethylene, polypropene, polyester, polymide, or an interpolymer is bound together with the hotmelt in an artificial turf stock material.

Backfixing of artificial turf stock material with hotmelts based on amorphous poly-&#x3b1;-olefins and/or modified amorphous poly-&#x3b1;-olefins

A polyolefin which contains the following monomer units:

Highly viscous, largely amorphous polyolefin

A process for tuft and filament bonding of unfinished carpet includes applying a coating composition which contains from 50% to 100% by weight of a substantially amorphous poly-&#x3b1;-olefin as a melt to the backside of a carpet material so as to obtain a coating weight of from 20 to 1,500 g/m, the melt viscosity of the coating composition at 190&#xb0; C. is in the range from 400 mPas to 10,000 mPas.
