Claims17
A polyolefin for floor coverings, wherein the polyolefin is a copolymer of ethylene, propylene and 1-butene comprising ethylene and propylene in a total amount of not more than 20% by mass and 80-98% by mass of 1-butene, with the sum of the proportions being 100% by mass, wherein the triad distribution for 1-butene triads determined by 13C-NMR has an isotactic proportion of 10-98% by mass, an atactic proportion of 1-85% by mass and a syndiotactic proportion of not more than 20% by mass, wherein the polyolefin has at least one melting peak in the DSC at a temperature in the range of 30-95° C. and wherein the isotactic proportion of the propene triads is 75-82%.
A polyolefin hot melt adhesive for nap and/or filament binding, wherein the polyolefin is a copolymer of ethylene, propylene and 1-butene comprising ethylene and propylene in a total amount of not more than 20% by mass and 80-98% by mass of 1-butene, with the sum of the proportions being 100% by mass, and wherein the triad distribution for 1-butene triads determined by 13C-NMR has an isotactic proportion of 10-98% by mass, an atactic proportion of 1-85% by mass and a syndiotactic proportion of not more than 20% by mass, wherein the polyolefin has at least one melting peak in the DSC at a temperature in the range of 30-95° C. and wherein the isotactic proportion of the propene triads is 75-82%.
A polyolefin heavy coating composition for the production of floor coverings, wherein the polyolefin is a copolymer of ethylene, propylene and 1-butene comprising ethylene and propylene in a total amount of not more than 20% by mass of 1-butene and 80-98% by mass, with the sum of the proportions being 100% by mass, and wherein the triad distribution for 1-butene triads determined by 13C-NMR has an isotactic proportion of 10-98% by mass, an atactic proportion of 1-85% by mass and a syndiotactic proportion of not more than 20% by mass, wherein the polyolefin has at least one melting peak in the DSC at a temperature in the range of 30-95° C. and wherein the isotactic proportion of the propene triads is 75-82%.
A floor covering comprising a polyolefin, wherein the polyolefin is a copolymer of ethylene, propylene and 1-butene comprising ethylene and propylene in a total amount of not more than 20% by mass and 80-98% by mass of 1-butene the sum of the proportions being 100% by mass, and wherein the triad distribution for 1-butene triads determined by 13C-NMR has an isotactic proportion of 10-98% by mass, an atactic proportion of 1-85% by mass and a syndiotactic proportion of not more than 20% by mass, wherein the polyolefin has at least one melting peak in the DSC at a temperature in the range of 30-95° C. and wherein the isotactic proportion of the propene triads is 75-82%.
