FIELD: technology of reprocessing of frothed polystyrene. SUBSTANCE: method involves heating and frothing at 100 C for 2-3 min, cyclic cooling by 15-19 C with frequency 0.8-1.0 cycle/s for 30-60 s and cooling up to 58-60 C at the rate 20-30 C/min. EFFECT: diminished frothing time by 11-15 times, enhanced elasticity of granules. 1 tbl
