Narrative:
While descending below FL190 the F900 aircraft we were operating went into a rapid and violent right 45 degree rapid roll also turned off the autopilot. We were being vectored around thunderstorms and were completely IMC. My sic called ATC to report the roll which we thought at the time was a burst from the storm off to our left. ATC informed us the roll was due to the wake a heavy A330 we were following. At no time prior to this call did ATC caution us about the A330. ATC apologized about the vector into the wake and asked if we had any injuries. We did not; just frightened passengers. Every time after this incident when we were passed to a different controller; they did caution us about the wake. Prior to entering into washington's airspace we were told to slow to 310kts (as was everyone else). While in washington's airspace we were vectored off course to better separation. We asked if they needed us to slow down and they informed us not to because they had multiple aircraft following behind us. If we were allowed to slow; we might have had adequate separation from the A330 to prevent the upset.
