i presume that what you mean is that you've converted to poly from sub-D. If i am correct, you have a poly framework attached to your poly object that you cannot identify.
Asumming that this is the nature of your question, the framework is caused by converting a sub-d to polygon BEFORE you go to standard sub-d mode. if you convert to poly while the sub-d is still in polygon edit mode, a poly shell is created that will be attached to the newly formed poly object.
When you convert your sub-d to polygons make sure that you are in the 'standard' mode for sub-d.
