# Will the rotation of a neutron star prevent it becoming a Black Hole?

This question, to me anyways, is basically a balancing act between 2 possibly opposing effects.

Take a neutron star with just too small a mass to overcome it's degeneracy pressure, failing to collapse into a Black Hole. (Chandrasekhar limit)

Now assume it acquires a bit more material, that has a small mass but has large angular momentum.

Would this extra angular momentum provide sufficient rotation act to stop further collapse or would this additional K.E. act as an effective mass, through $mc^2$, to actually promote a collapse into a Black Hole?
