Chlorosilyl-functional initiator

The synthesis of poly(dimethylsiloxane)macromonomers was also carried out anionically. The cyclic trimer D3 of dimethylsiloxane may be polymerized anionically, using lithium trimethylsilanolate as the initiator. Deactivation of the silanolate end groups may be performed with chlorosilyl functions. Yamashita et al. 29) successfully applied the unsaturated deactivators I and II... 

SI-NMP can also be carried out using an initiator/nitroxide bimolecular system [22]. In this strategy, an azo-based initiator functionalized with chlorosilyl groups was first attached to the sihcon wafer after immersion of the substrates in a toluene solution containing the azo derivatives. The formation of PBA brushes with thickness of 4—14 nm using two different azo initiators (AMCl and ATCl) was performed...
