Poly(vinyl alcohol) Mw 89,000-98,000, 99+% hydrolyzed - is a hydrophilic linear polymer which forms copolymers of vinyl alcohol and vinyl acetate. Hence, the structural properties of polyvinyl alcohol polymers depend on the extent of polymerization and hydrolysis.
P 7079 (OTTO) Poly(vinyl alcohol) Mw 31,000-50,000, 98-99% hydrolyzed Cas no 9002-89-5 - used for a variety of applications such as a stabilizer in the synthesis of nanoparticles.
