How to benefit from personal unions? I've played as Lithunia and had union with Poland, but ... as far as I understand at some point Poland will get own king and become separated again.

Is there any way to get union partner become the part of your country?

It takes half a century, but after that duration the nation leading a personal union can inherit or integrate their subject nation so long as the leading nation has more provinces than the subject country.

Inheritance can occur when a ruler dies. See the hovertip over the king in the diplomacy screen to see the probability statistic. Main influences are Diplomatic Reputation, Stability, and whether the countries share a culture group.

Another option, if the leader in the union has 190+ relations with the subordinate partner, then "Integrate" is a diplomatic process that will get the ball rolling on the integration and is similar to annexation.
