Synthesis of new types of polysiloxane based surfactants
Abstract
New types of amphiphilic polysiloxane diblock copolymers containing a pure polysiloxane backbone were prepared by the functionalization of poly(dimethylsiloxane)-block-poly(methylvinylsiloxane) copolymers, synthesized by ‘living’ anionic ring opening polymerisation of 1,3,5,7-tetramethyl-1,3,5,7-tetravinylcyclotetrasiloxane (D4v) and hexamethylcyclotrisiloxane (D3).
