Toluene → 1-Hexene

참여 물질

반응 단계

A copolymer of 1-hexene and 1,7-octadiene (molar charge ratio 90:10) was synthesized according to the general procedure in Example I. It had an inherent viscosity of 3.5 dl./g. and 25 percent gel. A solution of 43.3 grams of this copolymer and 95 grams of hexachlorocyclopentadiene in 750 ml. toluene containing finely dispersed gel was heated at 110° C. for 24 hours. After cooling, the reaction mixture was precipitated in excess methanol. The yield of the product was 51.5 grams, inherent viscosity 1.5 dl./g., gel 16 percent. An acetone-extracted sample contained 14.1 percent chlorine, indicating that about 70 percent of the double bonds in the original copolymer had reacted with hexachlorocyclopentadiene.
