The paper describes the synthesis of low molecular mass poly(allyl chloride) (PAC) (Mn = 856-3834 g mol-1) using Lewis acid (AlCl3, FeCl3, TiCl4) and Al powder. Branching in PAC was indicated on the basis of elemental analysis and 1H-NMR spectroscopy. Azidation of PAC could be carried out at 100°C by using NaN3 and DMSO as solvent. Curing of poly(allyl azide) (PAA) by cyclic dipolar addition reaction with EGDMA (ethylene glycol dimethacrylate, 5-45 phr) was investigated by differential scanning calorimetry and structure of cured polymer was confirmed by FTIR. A two-step mass loss was exhibited by uncured and cured PAA in nitrogen atmosphere. A mass loss of 20-28% (155-274°C) and 50-61% (330-550°C) was observed.
