Silicate anchored multifunctional initiator has moiety initiating ring opening living polymerization of lactone or ethylene oxide or cyclic siloxane monomer and other moiety for initiating living free radical polymerization of ethylenically unsaturated monomer. The monomers are reacted with the initiator in a one-pot, one-step reaction to cause living polymerization of both monomers and exfoliation of silicate layers to provide dispersed block copolymer silicate nanocomposite, with the junction of the two blocks being anchored to silicate layer and each block dangling therefrom.

One-pot, one-step in situ living polymerization from silicate anchored multifunctional initiator
