Embodiment 1
[0075] In this example, the polysiloxane-allyl compound shown in formula I was prepared from 2,2'-diallyl bisphenol A and hydrogen-containing polysiloxane HWG17606 through hydrosilylation, and the preparation method was as follows :
[0076] Dissolve diallyl bisphenol A and catalyst chloroplatinic acid completely with an appropriate amount of toluene, mix them, preheat to 60°C, add metered amount of hydrogen-containing polysiloxane drop by drop under constant stirring in a nitrogen atmosphere, and continue React until the signal peak (near 2145cm-1) of the Si-H bond in the infrared spectrum of the reaction mixture solution disappears or is very weak, while the allyl group signal peak (near 1635cm-1) remains strong, stop heating, and depressurize The solvent is removed to obtain a polysiloxane-allyl compound, the structure of which is shown in formula d.
[0077] The infrared spectrum characterization results of the prepared polysiloxane-allyl compound are as follows: figure ...
Embodiment 2
[0081] In this example, the polysiloxane shown in formula I was prepared from 3,3'-diallyl-4,4'diphenol ether diglycidyl ether and hydrogen-containing polysiloxane HWG17606 by hydrosilylation - allyl compound, the preparation method is as follows:
[0082] Completely dissolve 3,3'-diallyl-4,4'diphenol ether diglycidyl ether and 10ppm Karstd catalyst with an appropriate amount of toluene, mix, preheat to 70°C, and keep stirring in a nitrogen atmosphere Add the metered amount of hydrogen-containing polysiloxane dropwise, and continue the reaction until the signal peak (2145cm) of the Si-H bond in the infrared spectrum of the reaction mixture solution -1 near) disappeared or very weak, while the allyl group signal peak (1635cm -1 Nearby) still remain strong, stop heating, remove solvent under reduced pressure, obtain polysiloxane-allyl compound, its structure is shown in formula a.
[0083] Dissolve MX9000 and the compound of formula a prepared above with an appropriate amount ...
Embodiment 3
[0086] In this example, the polymer shown in Formula I was prepared from 1,1-bis(3,3'-diallyl-4,4'xylene)methane and hydrogen-containing polysiloxane HWG17606 through hydrosilylation. Siloxane-allyl compound, the preparation method is as follows:
[0087] Completely dissolve 1,1-bis(3,3'-diallyl-4,4'xylene)methane and 10ppm of Karstd catalyst with an appropriate amount of toluene, mix, preheat to 85°C, and place in a nitrogen atmosphere without Stop stirring and add metered amount of hydrogen-containing polysiloxane dropwise, and continue the reaction until the signal peak (near 2145cm-1) of the Si-H bond in the infrared spectrum of the reaction mixture solution disappears or is very weak, while the allyl group signal The peak (near 1635cm-1) still remained strong, the heating was stopped, and the solvent was removed under reduced pressure to obtain a polysiloxane-allyl compound, the structure of which was shown in formula b.
[0088] Dissolve MX9000 and the compound of formu...
