Templating organosilicate vitrification using unimolecular self-organizing polymers prepared from tandem ring opening and atom transfer radical polymerizations

Abstract

A unimolecular templating star-shaped polymer with a compatibilizing outer corona, prepared by tandem ROP/ATRP procedures, was dispersed into a thermosetting organosilicate. The organic polymer was thermalized to leave behind its latent image in the matrix with a pore size that reflected the size of the polymer molecule, and provided the expected reduction in dielectric constant.
