Hi Nick,
consider the full form of your expression poly=1 + x + x^2 + x^3 + x^4:
FullForm[poly]
this nearly looks like the list you want (besides reversion), only the
Head is Plus instead of List. But this is easily fixed by Apply:
List @@ poly
If you want to reverse the list, you may use Reverse.
hope this helps, Daniel
