Adjunct Professor of Polymer Science                                              

Ph.D., 1978, Case Western Reserve University; Research Scientist, Central R&D, Dow Corning Corporation, 1978 - present; Visiting Professor, Kyoto University, Japan, 1987 - 1988.

Prof. Graiver work's has been directed toward various aspects of preparation and characterization of organosilicon polymers. He has been studying the condensation kinetics of bulk polymerization, as well as emulsion and interfacial processes under different catalytic conditions. Fundamental research work also included silicone microemulsions, hydrolysis of chlorosilanes, block and graft copolymerization of polysiloxanes with organic polymeric systems. In addition to conventional linear polymers, hydrogels, branched (cross-linked) systems, hyperbranched structures and other dendritic silicone systems were also prepared and characterized.
