Environment - Non Weather Related; Procedure
Takeoff Runway 25R PHX closely behind [an] A321. Waited for the A321's rotation before starting my takeoff roll. On initial climb at about 200 FT AGL started getting into severe wake turbulence. The turbulence felt like a punch with a sharp left roll. After about 5 shots asked Departure for a 10 degree left turn off the ZEPER 1. Cause: insufficient separation between departing aircraft. Suggestions: more spacing between departing aircraft.
B737-800 Captain reported encountering 'severe' wake turbulence departing PHX in trail of an A321.
