Melt polymerization of low melt viscosity liquid crystal polymer |
| abstract |
The present invention provides a method for forming a high molecular weight liquid crystal polymer. The method comprises melt polymerizing two or more precursor monomers (e.g., acetylated or non-acetylated) in the presence of an aromatic guanamine oligomer. The inventors have discovered that the oligomer can reduce its melt viscosity when the viscous polymer is formed. The ability to reduce the melt viscosity in situ during melt polymerization enables the formation of high molecular weight polymers that exhibit low melt viscosity and can still be removed from the reactor vessel without curing therein. This not only improves the convenience of the treatment, but also achieves molecular weight even higher than conventional practice. |
