1-35. (canceled)
A functional filler comprising:
- an inorganic particulate material, wherein the inorganic particulate material has a d50 of less than about 10 μm;
- and
- a coating comprising a first compound including a terminating propanoic group or ethylenic group with one or two adjacent carbonyl groups.
A polymer composition comprising:
- polymer;
- and
- at least 3 wt. % of a functional filler,
- wherein the polymer comprises from 90 wt. % to 100 wt. % of a mixture of polyethylene and polypropylene, and wherein the functional filler comprises:
- an inorganic particulate material;
- and
- a coating comprising a first compound including a terminating propanoic group or ethylenic group with one or two adjacent carbonyl groups.
