Raising viscosity of gelatin solns. - using water-soluble maleic acid anhydride¨ polymers, useful in photography

Process using water-soluble maleic acid anhydride polymers, the water-soluble polymer comprises a mixed polymer of formula (I), where R = OM or morpholino; A = styrene, alpha-methyl-styrene, ethylene, propylene or butylene; M = H or alkali; x + y + z = 300-100,000, and n = 2-12. USE/ADVANTAGE - The...

Beschreibung
Zusammenfassung:	Process using water-soluble maleic acid anhydride polymers, the water-soluble polymer comprises a mixed polymer of formula (I), where R = OM or morpholino; A = styrene, alpha-methyl-styrene, ethylene, propylene or butylene; M = H or alkali; x + y + z = 300-100,000, and n = 2-12. USE/ADVANTAGE - The water soluble polymer is useful in raising the viscosity of gelatine solns., esp. photographic gelatine solns. for prodn. of silver halide recording materials. (0/0)
