Thermoplastic olefin composition, process of making the composition, articles formed from the composition, and a method of forming articles therefrom

A process of forming a thermoplastic olefin composition comprising:

• combining, based on the total weight of the composition, about 20 wt % to about 40 wt % polypropylene;
• about 20 wt % to about 70 wt % ethylene copolymer;
• and
• less than or equal to about 30 wt % linear low density polyethylene, to produce the thermoplastic olefin composition.

A thermoplastic olefin composition, comprising a reaction product of, based on the total weight of the composition:

• about 20 wt % to about 40 wt % polypropylene;
• about 20 wt % to about 70 wt % ethylene copolymer;
• less than or equal to about 30 wt % linear low density polyethylene;
• and
• a free radical initiator, a pre-radical controlling co-agent component, or both.

A process for vacuum forming an article, comprising:

• mixing about 20 wt % to about 40 wt % polypropylene, about 30 wt % to about 70 wt % ethylene copolymer, and less than or equal to about 30 wt % linear low density polyethylene to form a blend, based upon a total weight of the blend;
• and
• forming a sheet from the blend;
• heating the sheet to a softening temperature;
• disposing the sheet in a mold;
• and
• vacuum forming the sheet into an article.
