KURARAY POVAL™ L – low-viscosity PVA with low hydrolysis
KURARAY POVAL™ L grades are polyvinyl alcohols with a low degree of hydrolysis. Despite this, they are completely water-soluble. At 70-80 mol% hydrolysis, viscosity in a 4% aqueous solution ranges from 5 mPas to 8 mPas. These products are very effective as protective colloids in PVC suspension polymerisation.
