CV:

Akira Hirao was born in December 1947. Hereceived his Doctorate Degree from Department of Chemical Engineering, TokyoInstitute of Technology, Japan, in March 1975. After post-doctoral work in theUSA for two years, his professional carrier started at the Tokyo Institute ofTechnology progressed from Assistant Professor (1977-83), Associate Professor(1983-96), to Full Professor (1996-2013). He was Department Chairman four times,Vice-Dean two times, and the Head of Faculty. He became an Emeritus Professorof Tokyo Institute of Technology from April, 2013. He was a Chair Professor ofSoochow University from 2013 to 2015. He is now a Distinguished Chair Professorof National Taiwan University (Taiwan) and a Chair Professor of National ChiaoTung University (Taiwan).

 

He has been working in the area ofpolymer synthesis since 1975. Hisresearch interests are focused on the following areas: synthesis and living anionic polymerization ofnew functional monomers, precise synthesis of architectural polymers such as multiblockpolymers, exactly defined graft polymers, high-density comb-like polymers,chain-end- and in-chain-multi-functionalized polymers, multiarmed and multicomponentstar-branched polymers, and high-generation and high-molecular-weight dendrimer-likestar-branched polymers, and surface nanostructure control and analyses usingwell-defined perfluoroalkyl polymers.

 

In recent years, he received the Japan PolymerSociety Award (2010), the best award in polymer science in Japan, the PublicationAward from the Society of Rheology (USA) (2011), and the OutstandingAchievement in Polymer Science and Technology Award from the Japan PolymerSociety (2014). He has been a fellow academia in the Japan Polymer Societysince 2014. He has publishedmore than 300 papersin peer reviewed journals, 20 bookchapters (and two co-editors), andgiven 100 keynote, plenary, and invited lectures at international conferencesand more than 300 invited talks and lectures in Japan (~200 times) as well asoverseas (~100 times) including Polymer Society, Chemical Society,Universities, and companies.

 

Abstract:

The polymerization of 1,4-divinylbenzene (DVB)generally proceeds along with the unwanted addition reaction of propagatingchain-end species with the pendant double bond. As a result, highly branching occurs,followed by cross-linking among polymer chains to afford insoluble polymers.Therefore, DVB is usually used as a cross-linker, but not considered as amonomer. Very recently, we have first demonstrated that DVB undergoes theliving anionic polymerization by the addition of potassium tert-butoxide to afford the polymers with controllable molecularweights (Mn up to 60 500 g/mol)and narrow molecular weight distributions (Mw/Mn < 1.05).1 Furthermore, novel well-defined block polymers and star-branched polymershaving reactive PDVB segments have been successfully synthesized.2-4
