Thermoplastic Vulcanizate Compositions

A method of making a TPV composition, comprising:

• introducing an ethylene based copolymer to an extrusion reactor;
• introducing a thermoplastic polyolefin to the extrusion reactor;
• introducing a filler, an additive, or a combination of filler and additive to the extrusion reactor;
• introducing a first amount of one or more of an oil or a plasticizer to the extrusion reactor before a curative;
• introducing the curative to the extrusion reactor;
• introducing a second amount of one or more of an oil or a plasticizer to the extrusion reactor after the curative, wherein 3 wt % to 37 wt % of a total amount of the one or more of an oil or a plasticizer is added to the extrusion reactor before the curative and 63 wt % to 97 wt % of the total amount of the one or more of an oil or a plasticizer is added to the extrusion reactor after the curative;
• and
• dynamically vulcanizing the ethylene based copolymer with the curative in the presence of the thermoplastic polyolefin to form a TPV composition.
