Abstract
The present disclosure provides an article. The article includes an adhesive layer with two opposing surfaces. The adhesive layer includes (i) a functionalized ethylene-based polymer having a melt index from 0.1 g/10 min to 300 g/10 min; (ii) from 0.01 wt % to 45 wt % of a functionalized hydrocarbon; (iii) a tackifier; and (iv) optionally, a crosslinking agent.
Claims9
An article comprising:
- an adhesive layer having two opposing surfaces, the adhesive layer consisting of
- (i) from 20 wt % to 70 wt % of a functionalized ethylene-based polymer that is a maleic anhydride grafted ethylene-based polymer having a melt index from 0.1 g/10 min to 300 g/10 min;
- (ii) from 1 wt % to 45 wt % of a functionalized hydrocarbon that is a maleic anhydride grafted polybutadiene;
- (iii) from 15 wt % to 55 wt % of a tackifier;
- and
- (iv) from 0.1 wt % to 1.5 wt % of a crosslinking agent
- (v) optionally, a non-functionalized ethylene-based polymer that is not an ethylene/α-olefin multi-block copolymer;
- (vi) optionally, an additive selected from the group consisting of antioxidant, antiblock additive, and combinations thereof;
- a first layer in direct contact with a first surface of the adhesive layer, the first layer comprising a fabric comprising fiber selected from the group consisting of polyester fiber, polyamide fiber, cellulose fiber, and combinations thereof;
- and
- a second layer in direct contact with a second surface of the adhesive layer, the second layer consisting of (i) an ethylene/α-olefin multi-block copolymer having hard blocks and soft blocks and (ii) an optional additive selected from the group consisting of antioxidant, antiblock additive, and combinations thereof.
