It is shown that the first generation Grubbs Ru-carbene complex makes it possible to obtain these copolymers directly from monomers. In the course of one-pot synthesis, the metathesis polymerization of norbornene, which has a markedly higher ring strain, occurs first. Then, cyclooctene polymerizes and simultaneously an interchain cross-metathesis reaction takes place, during which the block structure of the copolymer is formed. Compared to the previously studied interaction of polynorbornene and polycyclooctene, the one-pot method makes it possible to obtain copolymers with a higher molar mass at a lower catalyst consumption.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181323756992">Впервые проведен однореакторный синтез статистических мультиблок-сополимеров норборнена и циклооктена. Показано, что Ru-карбеновый комплекс Граббса первого поколения дает возможность получать указанные сополимеры непосредственно из мономеров. В ходе однореакторного синтеза вначале происходит метатезисная полимеризация норборнена, обладающего существенно более высокой напряженностью цикла. Затем полимеризуется циклооктен и одновременно протекает межцепная реакция макромолекулярного кросс-метатезиса, в ходе которой формируется блочная структура сополимера. По сравнению с изученным ранее взаимодействием полинорборнена и полициклооктена однореакторный метод позволяет получать сополимеры с большей молярной массой при меньшем расходе катализатора.</p></trans-abstract><kwd-group xml:lang="en"><kwd>metathesis polymerization</kwd><kwd>one-pot synthesis</kwd><kwd>multiblock copolymers</kwd><kwd>Grubbs’ catalyst</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>метатезисная полимеризация</kwd><kwd>однореакторный синтез</kwd><kwd>мультиблок-сополимеры</kwd><kwd>катализатор Граббса</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы признательны Г.А.
