Chairman of The Sanmar Group N Sankar died on Sunday following a brief illness, family sources said.
Sankar had held various responsibilities in industry-organisations.
Sankar had joined Chemplast on May 4, 1967 as a trainee when his late father KS Narayanan had been promoter and director.
He had been involved in educational and charitable organisations like Sri Sankara Schools, Chennai and Willingdon Corporate Foundation.
“Sankar pushed international growth and investment to make Sanmar a leading player globally,” he added.
