Description

Методика опыта аналогична примеру 2. В реакцию берут 12,14 г октаметилциклотетрасилоксана и 0,0061 вес. % нормального тетрабутиламмонийфторида. После переосаждени  получают 9,95 г (82%) полидиметилсилоксана с TJ 1,21.The experimental procedure is similar to example 2. 12.14 g of octamethylcyclotetrasiloxane and 0.0061 wt. % normal tetrabutylammonium. After reprecipitation, 9.95 g (82%) of polydimethylsiloxane with a TJ of 1.21 is obtained.

Пример 4. Сополимеризаци  октаметилциклотетрасилоксана с цис-1,1,1-триметил-3 ,3,3-трифенилциклотрисилоксаном.Example 4. Copolymerization of octamethylcyclotetrasiloxane with cis-1,1,1-trimethyl-3, 3,3-triphenylcyclotrisiloxane.

Методика опыта, аналогична примеру 2. В реакцию берут 4,931 г октаметилциклотетрасилоксана , 7,393 г цис-1,1,1-триметил - 3,3,3 - трифеиилциклотрисилоксана и 0,01 вес. % тетраметиламмонийфторида.The experimental procedure is analogous to example 2. 4.931 g of octamethylcyclotetrasiloxane, 7.393 g of cis-1,1,1-trimethyl - 3,3,3-trifeiylcyclotrisiloxane, and 0.01 wt. % tetramethylammonium fluoride.

После переосаждеии  из метанола получают 9,81 г (79%) полимера с TI 0,81.After reprecipitation from methanol, 9.81 g (79%) of polymer with a TI of 0.81 is obtained.
