Grade
Partially neutralized polyacrylate( NP grade :Powder)
- i) NP-800
*Like following structural formula, the copolymerization ratios of acrylic acid are 65 mole percents and a grade with the highest acidity.Since degree of acidity is high, it is effective to blend to raise adhesive, when adding for poultice, or a medicine stable in acidic region.
- ii) NP-700
*Like following structural formula, degree of neutralization is 50 mole percents and this grade is extremely widely used.
- iii) NP-600
*Like following structural formula, the degree of neutralization is 70 mole percents and high grades.Since pH of aqueous solution(0.2wt%) is 7.0-7.4, in case it uses it for a poultice, it is effective of a stable medicine at an alkalis.
