In this paper we generate some new classes of entangled states of a two-mode Bose-Einstein condensate (BEC) in the presence of two- and three-body elastic as well as mode-exchange collisions. After introducing the general form of the time evolved state, various classes of entangled states are generated. Depending on the tunneling strength constants, two-, three- and four-partite entangled states are generated. Considering three-particle collision dramatically changes the generated entangled states. Moreover, in particular cases, the resulted states are non-entangled. The degree of entanglement for two-partite entangled states can be tuned via the number of BEC atoms i.e., the corresponding concurrence tends to its maximum value by increasing the number of atoms in the system.
