started working at the Institute of Organic Chemistry of the 

 U.S.S.R. Academy of Sciences. In 1954 he began work at the 

 Institute of Organo -Elemental Compounds of the U.S.S.R. Acade- 

 my of Sciences. Korshak has been a member of the Communist 

 Party of the Soviet Union since 1940. In 1953 he was elected a 

 Corresponding Member of the U.S.S.R. Academy of Sciences. 

 He was awarded Stalin Prizes in 1949 and in 1951. 



Korshak' s main works deal with the chemistry of high mo- 

 lecular compounds. He investigated the process of polyconden- 

 sation of dicarboxylic acids with diamines and glycols, and also 

 dihalide derivatives with aromatic hydrocarbons. He worked 

 out a theory of linear poly condensation. He proposed a classifi- 

 cation and nomenclature for high molecular compounds. A part 

 of Korshak' s work deals with the mechanism of the Friedel- 

 Crafts-reaction and with methods for synthesis of various or- 

 ganic substances. 



In August 1956, Korshak visited the United States to attend 

 the Sixth International Conference on Coordination Compounds, 

 New York.
