There is no specific condemnation of polygamy in the New Testament, except a recommendation from Paul to leaders in a specific area where monogamy was the norm. Paul had a lot of interesting comments about women and marriage that you won't find elsewhere in the Bible.
Jews practiced polygamy in Jesus' time and there's no record of his objection. Historical documents also show there were early Christians who practiced polygamy.
The suggestion that condemning divorce is somehow a condemnation of polygamy at the same time is counterintuitive.

There are a lot of good arguments about why polygamy is a bad idea, but you won't find them in the Bible. This is something that all of Christianity has in its past. If any, monogamy became the norm among Christians due to their adaptation to Roman cultural norms, which may be what Paul was suggesting to Timothy.
