Our interest has focused on the sythesis of multiphase block copolymers and polymers with complex architectures. Dendritic and multifunctional orthogonal initiators, living/controlled polymerization procedures, quantitative organic transformations and new monomers have been prepared and used for the construction of these complex materials including star-shaped, dendrimer-like star, hyperbranched, radical block copolymers (unimolecular micelles) and dendritic-linear architectures. Nanophase separated block copolymers having diverse morphologies and properites have been tailored to address such important issues in microelectronic fabrication as stress, dielectric constant, adhesion and lithography.
