Abstract
The present disclosure provides an article. In an embodiment, the article includes a first structural component and a second structural component. The first structural component includes a polycarbonate composition. The second structural component includes a polymeric blend of (i) an ethylene/α-olefin multi-block copolymer, and (ii) a functional polymer modifier that is an ethylene/ester copolymer. The second structural component is adhered to the first structural component.
Claims9
An article comprising:
- a first structural component comprising a polycarbonate composition;
- and
- a second structural component consisting of a polymeric blend consisting of (i) from 80 wt % percent to 90 wt % of an ethylene/α-olefin multi-block copolymer consisting of ethylene monomer and α-olefin comonomer, and (ii) from 20 wt % to 10 wt % a functional polymer modifier that is an ethylene/ester copolymer;
- wherein the ethylene/ester copolymer is an ethylene-based copolymer comprising an ester comonomer having the Structure (1)
- wherein each of R1 and R2 independently is a C1-C2 hydrocarbonyl group;
- and
- the second structural component is adhered to the first structural component.
