As I said in another post, this is not the case, but I also found what
Klatte did in related area. Klatte and Zacharias made poly(vinyl
esters) such as poly(vinyl chloroacetate) at Chemische Fabrik
Griesheim Elektron in 1912. Poly (vinyl alcohol) can be manufacturerd
from this family of polymers by saponification or transestrification.
