Abstract
A family of low-molecular-weight, main-chain thermotropic liquid-crystalline polyimides (TLC-PI) that are crosslinkable is disclosed. These all-aromatic TLC-PI are derived from (i) wholly aromatic and flexible diamine monomers, in which the linkage between the two aniline-ends contains a relatively high heat-tolerant but flexible chain constituted by two or more units of 1,4-phenoxy or 1,3-phenoxy or in combinations of both. Processes of making and using such all-aromatic TLC-PI is also provided.
