Предлагаетс способ получени кристаллического стереорегул рного полициклогексадиена-1 ,3 с т. пл. выше 200°С, заключаюищйс в проведении процесса полимеризации циклогексадиена-1 ,3 на -аллильных комплексах переходных металлов в качестве катализаторов, которые могут примен гьс как одни, так и вместе с электроноакцепгорпыми активирующими добавками, например с трихлорацетатом никел или хлоранилом.A method is proposed for the preparation of crystalline stereoregular polycyclohexadiene-1, 3 with m. Pl. above 200 ° C, I conclude in carrying out the process of polymerization of cyclohexadiene-1, 3 on -allyl complexes of transition metals as catalysts that can be used both alone and together with electron-accepting activating additives, such as nickel trichloroacetate or chloroanil.
В качестве углеводородных растворителей могут примен тьс алифатические или ароматические углеводороды, например гексан, бензол или толуол.Aliphatic or aromatic hydrocarbons, such as hexane, benzene or toluene, can be used as hydrocarbon solvents.
Экспериментальна методикаExperimental technique
жают в ампулу в услови х, исключающих попадание кислорода воздуха и влаги.They are placed in a vial under conditions that exclude ingress of oxygen and moisture.
Перед загрузкой ампулы откачивают и прогревают в вакууме при 300 -400°С в течение 10-15 мин с целью удалени оклюдированных газов.Before loading, the ampoules are pumped out and heated in vacuum at 300-400 ° C for 10-15 minutes in order to remove the occluded gases.
Компоненты катализатора в углеводородных растворах загружают в ампулу в токе сухого аргона из сосудов Шленка. Формирование каталитцческого комплекса провод т при 25°С в течение времени, завис щего от используемого катализатора.The components of the catalyst in hydrocarbon solutions are loaded into a vial in a stream of dry argon from Schlenk vessels. The formation of the catalytic complex is carried out at 25 ° C for a time dependent on the catalyst used.
После сливани растворов катализатора л-кротилникельхлорида и сокатализатора трихлорацетата никел (примеры 1 и 2) и .выдерживани в течение 30 мин растворитель отгон ют п замен ют новой порцией, которую ввод т в ампулу из сосуда ГПленка в токе сухого аргона.After merging the solutions of the catalyst l-crotyl nickel chloride and the nickel trichloroacetate cocatalyst (examples 1 and 2) and holding the solvent for 30 minutes, the solvent is distilled off and replaced by a new portion, which is introduced into the ampoule from the HPl vessel in a stream of dry argon.
Катализатор -кротилпикельхлорид или -аллилникельбромнд и сокатализатор хлоранил (примеры 4 и 5) ввод т в ампулу одноврел енно с растворителем. Формирование комплекса провод т в течение 5-10 мин приThe catalyst, crotyl chloride or allyl nickel bromnd, and chloranyl cocatalyst (Examples 4 and 5) are introduced into the ampoule simultaneously with the solvent. The formation of the complex is carried out for 5-10 minutes at
25°С до начала выпадени осадка, носле чего ампулу охлаждают, и раствор обезгаживали.25 ° C before the precipitation starts, but the ampoule is cooled and the solution is degassed.
Катализатор -кротилникельйодид (примеры 6 и 7) и растворитель бензол ввод т в ампулу из сосудов Шленка в токе аргона.Catalyst-nickel iodide catalyst (examples 6 and 7) and benzene solvent are introduced into the ampoule from Schlenk vessels in a stream of argon.
