Methyl vinyl ether → Methyl vinyl ether

Participants

Reaction Steps

Copoly(methyl vinyl ether:maleic anhydride)(50:50) (Grantrez AN-119 available from GAF)(20.6 grams) was suspended in 80 grams of water and heated on a steam bath to form a 20% solids clear solution of copoly(methyl vinyl ether:maleic acid) (50:50) in water. To 61.8 grams of the solution (containing 12.4 grams of copolymer and 8.26 grams (0.072 mole) of maleic acid)) was added 4.0 grams (0.072 mole) of potassium hydroxide in order to half-neutralize all maleic acid present. Glycerol (9.3 grams) was also added as a plasticizer. The impedance of a bioelectrode prepared with the material was 33 Kohms.
