Novel self-reinforced polymer composites of polyetherimide and a melt processable wholly aromatic polyester are prepared according to this invention. The wholly aromatic polyester exhibits anisotropic properties in the melt phase. Mixing is carried out at a temperature at which both the polyetherimide and the wholly aromatic polyester are melt processable. The products of this inven- tion comprise about 35 to 95 percent by weight of wholly aromatic polyester, which is in the form of predominantly unidirectionally oriented continuous fibers primarily in the range of about 1 to 10 micrometers in diameter, distributed in a matrix of polyetherimide. The polymer composites of this invention have high tensile strength, high modulus, satisfactory elongation, good impact strength, and good high temperature properties.
