Narrative:
On slc 124.35 we slowed to .72 to climb to 360 for the performance charts as it was reported smoother; when we reached FL360 we began getting mountain wave. It increased to moderate chop and we fell below green dot I had my first officer (first officer) advise ATC we needed to descend. They said not now; I came on and said 'we needed to descend immediately' they gave us a heading and still wouldn't descend I advised my first officer if we need to descend; we will but we were well above the stick shaker. If needed I would have declared and emergency and initiated a descent.when an aircraft says they 'need to descend immediately' that should be taken by ATC as immediate.
