Olga Bogdanova
In 1941—1942 A. A. Balandin, O. K. Bogdanova, and A. P. Shcheglova developed and implemented at a synthetic rubber factory a method for producing a gas-resistant (polysulfide or thio) rubber, which was widely used in the production of a “self-tightening” – or, more accurately, “self-sealing” when struck by bullets – coating for aircraft fuel tanks.
