Amphoteric Polymers to Improve Paper
The objective of the present work is to evaluate the application of an amphoteric polymer, with acidic and basic groups on the polymer chain, as a paper dry strength additive. The polymer studied here is random terpolymer of high electrostatic charge density, and high molecular weight. The results of our work showed that the balance between the charge densities of the surface and the polymer st...
متن کاملAmphoteric Colloids
1. When we plot the values of osmotic pressure, swelling, and viscosity of gelatin solutions as ordinates over the pH as abscissae, practically identical curves are obtained for the effect of monobasic acids (HCl, HBr, HNO(3), and acetic acid) on these properties. 2. The curves obtained for the effect of H(2)SO(4) on gelatin are much lower than those obtained for the effect of monobasic acids, ...
متن کاملRaman spectroscopic study of the structure of water in aqueous solutions of amphoteric polymers.
Methacrylic acid (MA) and [3-(methacryloylamino)propyl]trimethylammonium chloride (MAPTAC) were polymerized to give amphoteric copolymers with various compositions. The structure and H-bonding of water in an aqueous solution of the copolymer were analyzed using the contours of the O-H stretching in the polarized Raman spectra. For comparison, the H-bonded network structure of aqueous solutions ...
متن کاملAmphoteric Behavior of Complex
The hypothesis that a mixture of two ampholytes behaves, within certain limits, as an individual (1) with characteristics distinct from either component can also be semiquantitatively tested by certain conductivity experiments. These are based on the observation that the addition of such a substance as gelatin markedly decreases the observed conductivity of a phosphate solution. The magnitude o...
متن کاملAmphoteric Behavior of Complex Systems
The amphoteric behavior of a system of two amphoteric components is theoretically examined; and this is shown to correspond more nearly with certain of the physical and chemical behaviors of living tissues than does the concept of a simple ampholyte.
