Процесс полимеризации осуществл ют при . Продолжительность процесса 2-3 ч. При достижении конвёр- 20 сии 94% в латекс ввод т гелеоодержащий хлоропрановый гомополимер в количестве 5-50%, а температуру полимеризации повышают до .40°С. После полного превращени  мономера в полимер 25 (97-99% конверсии) ввод т антиоксидант в количестве 2 вес,% на 100 вес. полимера. Выделение и сушку провод т обьп1ным способом.The polymerization process is carried out at. The process takes 2-3 hours. When convection reaches 94%, a gel-containing chloropranic homopolymer in an amount of 5-50% is introduced into the latex, and the polymerization temperature is increased to .40 ° C. After the monomer is completely converted to polymer 25 (97-99% conversion), antioxidant is added in an amount of 2% by weight per 100% weight. polymer Isolation and drying are carried out in a solid manner.

Пример 1. Полимеризацию провод т вышеописанным способом. Добав-л ют 5% гельсодержащего хлоропренового гомополимера на 95% линейного хлоропренового гомополимера.Example 1. The polymerization was carried out as described above. A 5% gel-containing chloroprene homopolymer is added to the 95% linear chloroprene homopolymer.

Пример 2. Аналогичен примеру 1, но добавл ют 10% гел&содержащего хлоропренового гомополимера на 90% линейного хлоропренового гомополимера .Example 2. Similar to Example 1, but adding 10% gel & chloroprene containing homopolymer to 90% linear chloroprene homopolymer.

Пример 3.Аналогичен примеру 1,но добавл ют20% гельсодержащего хлоропренового гомополимера на 80% линейного хлоропренового гомополимераExample 3. Analogous to example 1, but adding 20% of a gel-containing chloroprene homopolymer to 80% of a linear chloroprene homopolymer.

Пример 4. Аналогичен примеру 1, но добавл ют 50% гельсодержащего хлоропренового гомополимера на 50% линейного хлоропренового гомополимера .Example 4. Similar to Example 1, but 50% of a gel-containing chloroprene homopolymer is added to a 50% linear chloroprene homopolymer.

Пример 5. Берут 100%-ный хлоропреновый гомополимер. Полимеризацию ведут обычным способом.Example 5. Take 100% chloroprene homopolymer. The polymerization is carried out in the usual way.
