The behavior of a dense non-concatenated ring polymers within a confined spherical geometry is investigated. By increasing the temperature of a part of each chain, the activity based segregation is observed. We showed that introducing the activity in the system changes the topological state of the chains irrespective of the constraint imposed by the confinement. The dynamics and size analysis indicate that the chains swell when a part of it have its temperature increased. The swelling allow mutual threading of ring. We conclude that the enhance of mutual threading between chains due to thermal anisotropy, together with the chains' topological state drive the system into a kinetically arrested state.
