Summary

Ring opening metathesis polymerization (ROMP) of 2-trimethylsilylbicyclo [2.2.1]-hept-2,5-diene (I) with a tungsten hexachloride/tetramethyltin co-catalyst system yields poly[(2-trimethylsilyl-2-cyclopentene-1,4-diyl) vinylene] (II). The product polymer (II) has been characterized by1H,13C,29Si, IR and UV-VIS spectroscopy. Its molecular weight distribution has been determined by gel permeation chromatography (GPC), its thermal stability by thermogravimetric analysis (TGA) and its glass transition temperature (Tg) by differential scanning calorimetry (DSC).
