A modüle M is called cq>olyform modüle if for any small submodule N of M, Hom(M,N/K)=0 for ali submodules K of N. It is shown that rational numbers, and in general, fields of fractions of integral domains are copolyform modules and for a cq>olyform and lifting modüle M, S=End(M) is left and right principally projective ring, and if M is copolyform and lifting modüle then S=End(M) is left and right şemihereditary ring.
