Popis:	By electron spin resonance, ultraviolet-visible and infrared spectroscopy, and chromatography, calorimetry, elemental analysis and gravimetric methods, we determined the low-temperature impact of molecular chlorine on monomers and the free radicals that spontaneously form. The radicals that formed initiated the polymerization and chlorination reactions that occurred during the mixture of chlorine+monomer, which were prepared at 77 K and heated to 300 K. For the monomers that were in solid state at 300 K, the reactions proceeded in the temperature range near the chlorine melting point (170 K), whereas for the monomers that were in the liquid state at 300 K, the reactions occurred in the temperature range near the monomer melting point.
