Description
За последнее врем в промышленносп интересуютс новыми высокотеплостойкими полимерами, в которых силоксановые св зи чередуютс с силфениленовыми группировками:Recently, in the industry they have been interested in new highly heat-resistant polymers in which siloxane bonds alternate with silphenylene groups:
. I(. I (
- - СбН4 - Si - о Si - СбН4 - Si - О -- - SbH4 - Si - o Si - SbH4 - Si - O -
IIiIii
Дл получени подобных полимерных соединений используютс группировки, в которых фениленова группа расположена между двум атомами кремни , например:To obtain such polymeric compounds, groups are used in which the phenylene group is located between two silicon atoms, for example:
С1 R3-xSiC6H4SiR3-j Clj, (х и у равны 3, 2 или 1).C1 R3-xSiC6H4SiR3-j Clj, (x and y are 3, 2 or 1).
Однако до насто щего времени известен только один, предложенный Грииь ром и крайне неудобный дл практического использовани , способ получени подобных мономеров.However, until now, only one method proposed by Griyrom and extremely inconvenient for practical use, a method of producing such monomers, is known.
Разработан новый способ получени бис-(хлоралкилсилил)бензолов , заключающийс в том, что, с целью проведени процесса в более м гких услови х (атмосферное давление) eтилдиxлopcилaн конденсируют с хлорфенилметилдихлорсиланом при 600-700°в паровой фазе.A new method has been developed for the preparation of bis- (chloroalkylsilyl) benzenes, which consists in the fact that, in order to carry out the process under milder conditions (atmospheric pressure), ethyl dichlorosilane is condensed with chlorophenylmethyl dichlorosilane at 600–700 ° in the vapor phase.
Описанный способ может быть осуществлен в форме непрерывного процесса пропусканием паров реагентов через трубчатый или подобный реактор.The described method can be carried out in the form of a continuous process by passing reagent vapors through a tubular or similar reactor.
