Patent number: 4417043Abstract: A polymer capable of forming an anisotropic melt characterized in that the polymer chain includes residues of cross-linking reactants at a concentration sufficient to give a polymer with a melt viscosity of not greater than 10.sup.7 Nsec/m.sup.2 measured by capillary rheometry at a shear rate of 10.sup.4 N/m.sup.2. The polymers exhibit favorable shear dependent viscosity characteristics in that the viscosity is high under low shear conditions and is low under high shear conditions, as judged by the viscosity characteristics of polymers of the same composition but not containing the residues of cross-linking reactants.Type: GrantFiled: January 5, 1981Date of Patent: November 22, 1983Assignee: Imperial Chemical Industries PLCInventors: Frederic N. Cogswell, Brian P. Griffin, Clive P. Smith
