Abstract
The invention provides a composition comprising the following components: A) an olefin-based polymer; B) an anhydride and/or carboxylic acid functionalized olefin-based interpolymer comprising the following properties: i) a melt viscosity, at 190° C., less than, or equal to, 10,000 cP, and ii) a density from 0.900 to 0.950 g/cc.
Claims13
A composition comprising the following components:
- A) from 40 wt % to 70 wt % of a propylene-based polymer;
- B) from 1 wt % to 20 wt % of an anhydride and/or carboxylic acid functionalized olefin-based interpolymer comprising the following properties:
- i) a melt viscosity, at 190° C., less than, or equal to, 10,000 cP, and
- ii) a density from 0.900 to 0.950 g/cc;
