Description

Изобретение относитс  к способам полученн  карбоцепных полимерюв с концевыми ре кщю носпособнымн группамн, способных к реакцн м удпн енн  Н сшнвани в нроцессе вулканнзатщи. Эти полимеры наход т применение дл  получени  покрытий, клеев, герметиков, формующихс  составов Н т.д.. Известен способ получени  ymjyaxx. карбоцепных полимеров с концевыми карбоксильными группамн радикальной растворной полимеризацней или сополнмеризацией ненасыщенных мономеров (дивнн л, изопрен, акрилонитрил и лругке) с использованием в качестве инициатора-7,7 (7 -, tyuM Н валериановой кислоты). Однако зтим способом не могут быть получены полимеры с концевыми галоидными атомами. Полученный эгам способом полимер отверждаетс , как правило, только при повышенных температурах (60-80°С). Целью предлагаемого изобретени   вл етс  ра аботка способа получени  жидких полимеров с концевыми реакционнослособными галоидными «томами, иапример с атомами брома, наличие которых позвол ет проводить отверждение полифункциональными аминами как при повьшкиной, так и при комнатной температурах, и имеющих высокукс жизнеспособность. Сущность предлагаемого изобретени  соспжт в том, что полимеризаци  сопр женных диенов или их сс 1ол меризаци  с винильными мономерами проводитс  в растворе в присутствии азодинитрйльного инициатора бисструктуры, содержащего концевые алифатические атомы брома следующей формулы 3СМз Bf-CHj.-fCN.,),-C-N--N-C- CHj -CHjBf гдеп 1. Процесс полимеризации или сополимеризацкн провод т в органическом растворителе, шшр мер в ацетоне, при 50-9С| преимущественно 70° Цв течедае 30-50 час, в прису-гствии инициатора б,б аэобис (Ь циаН - Н - бромпентана) в количествеГ2-10 вес.ч. После окончанн  полнмеризации непрореагировавший мовомер удал ют иотарением (дегазацией), полимер отмывают от продуктов распада инициатора , зшфавл ют ангаоксидантом и сушат под вакуумом при температуре не выше 70°С,This invention relates to methods for the production of chain-chain polymers with terminally capable groups that are capable of reactive reaction in a volcannical procession. These polymers are used to obtain coatings, adhesives, sealants, molding compounds H, etc .. A method is known for producing ymjyaxx. carboxyl polymers with terminal carboxyl groups in radical solution polymerization or co-pollenization of unsaturated monomers (divnl, isoprene, acrylonitrile, and lrugka) using 7,7 (7, tyu M H valerianic acid) as an initiator. However, polymers with terminal halogen atoms cannot be obtained by this method. The polymer obtained by the method of aegam cures, as a rule, only at elevated temperatures (60-80 ° C). The aim of the invention is to work out a process for the production of liquid polymers with terminal reactive halide volumes, for example, with bromine atoms, the presence of which allows curing with polyfunctional amines at both povshkina and room temperatures, and having high viability. The essence of the proposed invention is that the polymerization of conjugated dienes or their copolymers with vinyl monomers is carried out in solution in the presence of an azodinitrile bissue initiator containing terminal aliphatic bromine atoms of the following formula 3CM3 Bf-CHj.-fCN. -NC-CHj -CHjBf, where 1. The polymerization process or copolymerisation process is carried out in an organic solvent, the concentration of the measures in acetone, at 50-9C | Preferably, 70 ° Tsv flowed for 30-50 hours, in the presence of the initiator b, b aeobis (b ciaH - H - bromopentane) in the amount of 2-10 weight.h. After the completion of the complete merization, unreacted movomer is removed by evaporation (degassing), the polymer is washed from the decomposition products of the initiator, spelled with an antioxidant and dried under vacuum at a temperature not higher than 70 ° C,
