liquid crystal polymers

[¦lik·wəd ¦krist·əl ′päl·ə·mərs]
(organic chemistry)
Aromatic polyester copolymers that have characteristically high-temperature resistance, yet can be melted and molded. Upon melting, the polymer chains undergo parallel ordering in the direction of the flow, resulting in superior mechanical properties in that direction.
