Abstract
A process for lessening shear-induced reduction of fiber length in a melt processable, fiber reinforced polymer composition, and compositions useful in and obtained from such process, comprising the steps of: admixing a first polymer, the first polymer being a thermoplastic polymer, with a second polymer being TLCP, and a reinforcing fiber; and subjecting the composition to shear, wherein the first and second polymers have melt processing ranges that overlap over an overlapping melt processing range; and the second polymer is partly immiscible with or immiscible with the first polymer when mixed with the first polymer within the overlapping melt processing range.
