В лабораторных услови х нроведены испытанн  1- (3,5-дн-7ре.бутил-4-окснбензнл) -3метилпиразолона-5 (Озоннна-37) и в светлых резинах, изготовленных но стандартной рецептуре на основе НК «светлый крен, с введением парафина н без нарафина.In laboratory conditions, tested 1- (3,5-dn-7re.butyl-4-oxnbenznl) -3methylpyrazolone-5 (Ozonnna-37) and in light rubber, manufactured using the standard recipe based on NK “light heel, with paraffin n without narafina.

В процессе испытаний определ лись фнзико-механнческне характеристики резин при нормальных услови х (НУ) и после старени  при 90°С в течение 3, 5 и 10 сут, стойкость резин к многократному раст жению, а также озоностойкость резин. Эталонами сравнени   вл лись АО-2246 и ТБТМ.During the tests, the fnziko-mechanical characteristics of rubber under normal conditions (NU) and after aging at 90 ° C for 3, 5 and 10 days, the resistance of rubber to repeated stretching, as well as the ozone resistance of rubber were determined. Reference standards were AO-2246 and TBTM.
