description In an embodiment, a thermoplastic vulcanizate (TPV) composition includes a rubber, a thermoplastic polyolefin, and a polyhedral oligomeric silsesquioxane, wherein: a concentration of the rubber is from 10 wt % to 80 wt % based on a combined weight of the rubber and the thermoplastic polyolefin; a concentration of the thermoplastic polyolefin is from 20 wt % to 90 wt % based on the combined weight of the rubber and the thermoplastic polyolefin; and a concentration of the polyhedral oligomeric silsesquioxane is from 0.1 wt % to 20 wt % based on the total weight of the TPV composition. In another embodiment, a process for preparing a dynamically vulcanized thermoplastic vulcanizate composition includes melt processing under shear conditions at least one thermoplastic resin, at least one rubber, at least one curing agent, and at least one polyhedral oligomeric silsesquioxane; and forming a dynamically vulcanized thermoplastic vulcanizate composition. In another embodiment, a pipe is provided.
