Alle Zukunft mit solaren Ressourcencrystalline polymer, polyphenylene sulfide (PPS). The PPS-based composites exhibit excellent chemical and solvent resistance and good thermal stability. However, PPS unidirectional composites retain only about 30% of their room temperature strength at 350°F.(1) Therefore, use of PPS composites as st

Thomas K?stner,Andreas Kie?ling such as ethylene oxide and caprolactam, and Zieglar-Natta ring-opening polymerization of cyclic olefins are well known. In a general research program designed to investigate free radical ring-opening polymerization in our laboratories, it has been found that a wide variety of unsaturated cyclic mon
