abstract

Polymeric optical fibers are generally manufactured in the same manner as traditional glass (silica) fibers. As technology advances, more efficient, cost effective materials and processes are being developed to serve the duties of optical materials within networks. Traditional polymer optical fibers are comprised of hydrocarbon amorphous polymers and include polymethyl methacrylate (PMMA) and polystyrene (PS). These types of polymers have inherent issues in optical applications such as their signal absorption loss. This is largely due to the vibration of the carbon-hydrogen (C-H) bond contained in the polymer backbone. Therefore, to broaden the scope of polymer optical fibers, novel exotic amorphous polymers are being developed. One such polymer family, reported to have excellent optical properties, is perfluorocyclobutyl aryl ethers (PFCB), which do not exhibit the strong C-H vibrations associated with absorption loss. At this time, little is known of the intrinsic properties of PFCBs as well as the behavior of the polymer melt during extrusion. This work will review the thermal and rheological properties of two PFCB polymers: biphenylvinyl ether (BPVE) and hexafluoroisopropylidene vinyl ether (6F). The information gathered from the analysis of these two intrinsic properties will be used as the input data for a fiber extrusion simulation model, FiSim. The application of the FiSim software was done in order to produce a viable limited range of process conditions for which fibers could be melt spun.
