The relationship between processing condition

microscopic morphology and mechanical properties of in-situ composite or blend of a thermotropic liquid crystalline polymer (TLCP) with polycarbonate (PC) was investigated. The processing condition

such as melt temperature

has a striking influence on the mechanical properties. The tensile strength of the blend is slightly higher than that of PC because the TLCP phase assumes a spherical shape in the center region of the specimen at low melt temperature of 270℃.At meilt temperature of 310℃

the blend exhibits great strength due to in-situ formed fibers of the disperse TLCP phase in PC matrix

and reinforced effect isenhanced appreciably. The tensile strength and modulus of the TLCP contribution in composite are much higher than those of the pure TLCP.
