PBT, PET, and PC are matrix polymers that have been Molded blends of a polyester-type thermotropic LCP with poly(ethyleneĢ.6-naphthalate). In this paper we focus on twin-screw extruder blended and injection The blends have been processed byĮxtrusion, melt spinning, injection molding, and compression molding. Commercial or experimental LCPs haveīeen blended with many thermoplastics, e.g., poly(butylene terephthalate) (PBT) (3, 5), poly(ethylene terephthalate) (PET) (6-10),Īnd polycarbonate (PC) (5, 1115). Several researchers have studied blends of thermotropic LCPs and Process because of its relatively low melt viscosity. Of a thermotropic LCP can also make some thermoplastics easier to Matrix polymer or to improve its dimensional stability. LCPs are blended with thermoplastics mainly to reinforce the Good properties of LCPs can be transferred into a more flexible matrix By blending thermotropic main-chain LCPs withĮngineering thermoplastics, the highly ordered fibrous structure and Processing combined with high performance characteristics makes theīlend composed of thermotropic LCP and engineering plastics veryĪttractive (3, 4). The mechanical properties are also of interest (3). The blends of LCPs with other engineering plastics to enhance Of their potential application as ultra-high strength fibers and moldedĪrticles. Thermotropic liquid crystalline polymers (TLCPs) are attractive because There has been aĬonsiderable interest in liquid crystalline polymers (LCPs), especiallyĪfter the development of high modulus and high strength fibers preparedįrom the lyotropic aromatic polyamides (aramids) by DuPont (1, 2).
