Not sure how these handle containers. Can't seem to locate any info about people growing them in this way, Everything I've found has suggested little more than that they grow quickly, can attain a height of around 40 feet and that they are hardy to zone 4.
There are a couple of different cultivars out there for this plant, perhaps one of them may be more suited for container use or perhaps just less spreading through suckers. May be worth looking into.
Perhaps your best bet may be to contact one of the many vendors out there that sell them.
