ABSTRACT
Based on historical data halide modification (HM) of high molecular compound was carried out in 1859, natural rubber (NR) was exposed to modification and, in addition to that, NR was dissolved in perchloromethane, through which chlorine gas was run through. Modified NR is powder product with content of fixed chlorine not over 6268% m., which did not have properties of elastomer [1, 2]. The HM of NR may be referred to one of the first attempt of commitment of new properties to polymer with help of carrying out of chemical modification.
