Abstract
1,231,324. Polyvinyl alcohol. E. I. DU PONT DE NEMOURS & CO. 24 Feb., 1969 [23 Feb., 1968], No. 9820/69. Heading C3P. The water slurrying properties of a polyvinyl alcohol which is at least 70% alcoholysed are improved by heating to at least 50‹ C. in a 2-20% wt. solution of acetic acid in methanol and/or methyl acetate optionally containing up to 8% of water.
