Пример 2. На 1ОО г 2%-ного рас.твора бутадиеннитрильного каучука в диметилформамше при 5О С, медленно, в течение S-1О мин добавл ют заранее приготовлен 1ую гмесь (3,6 г) брома и (8,4г) д метилформамида , что соответствует 30%ному раствору брома в диметилформамнде.Example 2. On 1OO g of 2% dissolving of butadiene nitrile rubber in dimethylformacch at 5 ° C, the first mixture (3.6 g) of bromine and (8.4g) d of methylformamide are added in advance for S-1O minutes That corresponds to a 30% solution of bromine in dimethylformamde.

Придобавлении полученного бромирова ного бутадиеннитрилъного каучука к смолам и композици м повышаетс  огнестойкость , в частности при введении в композицию состава: эпоксидна  смола ЭЯ-20 с отвердителем УП-583.The addition of the obtained brominated butadiene nitrile rubber to resins and compositions increases the fire resistance, in particular, when the composition is introduced into the composition: eYa-20 epoxy resin with the hardener UP-583.

Известные добавки того же назначени , например хлорнаирит, вводимые в ту же композицию по сравнению с предложенным продуктом имеют более низкие показатели (см. таблицу).The known additives of the same purpose, for example, chlarnite, introduced into the same composition have lower indices compared with the proposed product (see table).
