ABSTRACT:
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 invention 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.
