Narrative:

Immediately after encountering severe rime ice and turbulence, I asked center for a lower altitude. Approximately 30 seconds later a rate of descent of 3000 FPM was arrested at 500' below the assigned altitude. I did call out of the assigned altitude to inform ATC. ATC then cleared me to 5000'.
