A ring is called right SAP if every right simple module over it is absolute
ly pure. In this paper we prove that every right SAP ring is semiprimitive
and that the homomorphic image and the center of an right SAP ring are also
right SAP. We also show that the sum of all absolutely pure minimal submod
ules of any module is a fully invariant submodule. As an application, we gi
ve a decomposition of some selfinjective rings.
