Notes:
Poly{1-[4-(2-chloroethyl)phenyl]ethylene} (3) was synthesized by bulk polymerization of 4-(2-chloroethyl)styrene (6) in two steps from commercial products. The polymer was characterized by means of GPC (weight-average molecular weight M̄w = 85 000 and number-average molecular weight M̄n = 63 500), 1H NMR and 13C NMR spectroscopy. The first stage of thermal degradation begins at 290°C and ends at about 410°C. The overall activation energy was calculated to be 43 kcal · mol-1 (180 kJ · mol-1). The solid residue was crosslinked and insoluble. The volatile products, identified by gas chromatography-mass spectroscopy (GC-MS), were chiefly hydrogen chloride, dichloromethane and monomer. In a strongly basic medium, nucleophilic substitution of chlorine was achieved without elimination.
