Abstract

A tile comprising the following components: A) a first film formed from a first composition comprising the following: i) a functionalized olefin-based polymer comprising one or more chemical groups selected from the following: a) a carboxylic acid, and/or b) an anhydride, and, optionally, c) an amino or an amine; and ii) a functionalized styrenic block copolymer, comprising, in polymerized form, styrene, and ethylene and/or at least one alpha-olefin, and comprising one or more chemical groups selected from the following: a) a carboxylic acid, and/or b) an anhydride; and B) a substrate comprising at least one layer formed from a second composition comprising a propylene-based polymer; and wherein the first film covers at least one surface of the substrate.

First claim

We claim:

1. A tile comprising:
A) a first film formed from a first composition comprising the following:
i) a functionalized olefin-based polymer comprising one or more chemical groups selected from the following: a) a carboxylic acid, and/or b) an anhydride, and, optionally, c) an amino or an amine; and
ii) a functionalized styrenic block copolymer, comprising, in polymerized form, styrene, and ethylene and/or at least one alpha-olefin, and comprising one or more chemical groups selected from the following: a) a carboxylic acid, and/or b) an anhydride; and

B) a substrate comprising at least one layer formed from a second composition comprising a propylene-based polymer;
C) a UV-curable urethane-acrylate top coat layer applied onto and in contact with the first film; and
wherein the first film covers at least one surface of the substrate.

2. The tile of claim 1 , wherein the first composition comprises less than 0.001 wt % of an isocyanate compound, based on the weight of the first composition.

3. The tile of claim 1 , wherein the first composition is halogen free.

4. An article comprising the tile of claim 1 .

5. The tile of claim 1 , wherein the functionalized olefin-based polymer is a functionalized ethylene-based polymer.

6. The tile of claim 1 , wherein the functionalized olefin-based polymer is a functionalized ethylene/α-olefin interpolymer, selected from the group consisting of the following: an anhydride-functionalized ethylene/α-olefin interpolymer, a carboxylic-acid-functionalized ethylene/α-olefin copolymer, an hydroxy-functionalized ethylene/α-olefin copolymer, an amine-functionalized ethylene/α-olefin copolymer, and a combination thereof.

7. The tile of claim 1 , wherein the functionalized styrenic block copolymer is selected from the group consisting of the following: an anhydride-functionalized styrenic block copolymer, a carboxylic-acid-functionalized styrenic block copolymer, an hydroxy-functionalized styrenic block copolymer, an amine-functionalized styrenic block copolymer, and a combination thereof.

8. The tile of claim 1 , wherein the weight ratio of the functionalized olefin-based polymer to the functionalized styrenic block copolymer is from 2.0/1.0 to 6.0/1.0.
