Abstract
Abstract Provided is a carpet tile produced by using as a backing material a mixture which contains a solvent deasphalted asphalt and a copolymer of an olefin and a polar monomer, or a mixture which contains an amorphous polyolefin in addition to the above components. After applying the mixture as a hot melt to the back of carpet material, the backed carpet material is cooled and then cut or punched to produce the carpet tile.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
88 words
Method of making a carpet tile, which comprises heat-melting a mixture at 100°-240° C., said mixture containing (a) 100 parts by weight of a solvent deasphalted asphalt and (b) 10 to 70 parts by weight of a copolymer of an olefin and a polar monomer with the polar monomer content of the copolymer being 0.5 to 20% by weight, backing a carpet material with the molten mixture, cooling the backed carpet material and then cutting or punching the backed carpet material as desired to produce the carpet tile.
Claim 2
Dependent Claim
88 words
Method of making a carpet tile, which comprises heat-melting a mixture at 100°-240° C., said mixture containing (a) 100 parts by weight of a solvent deasphalted asphalt and (b) 10 to 70 parts by weight of a copolymer of an olefin and a polar monomer with the polar monomer content of the copolymer being 0.5 to 20% by weight, backing a carpet material with the molten mixture, cooling the backed carpet material and then cutting or punching the backed carpet material as desired to produce the carpet tile.
Claim 3
Dependent Claim
