Acrylamide, acrylic acid copolymer

In the case of acrylamide-acrylic acide copolymers, such a prediction requires a good knowledge and understanding on the three following aspects ... [Pg.116]

In recent works, we have studied the kinetics of both hydrolysis and degradation of a acrylamide-acrylic acid copolymer containing 17% of acrylate groups. The purpose of this paper is to give some predictions of the thickening properties evolution based upon semi-empirical viscosity laws. [Pg.117]

We have previously performed a systematical study of the degradation of a acrylamide-acrylic acid copolymer called sample C( of acrylate content r — 17% and molecular weight Mw — 6 106 ) prepared by... [Pg.118]

We have recently performed systematical measurements of the intrinsic viscosity of acrylamide-acrylic acid copolymers for large ranges of r and a, in the presence of CaCl2(26). Our results show that the empirical relation (14) can be extended to the case of divalent cations by using the value of 7 given in relation (15). It should then possible to predict the variation of intrinsic viscosity at infinite dilution, but at finite concentration the formation of aggregates makes difficult the determination of the Huggins constant.

In this work, we propose a method based on different combined semi-empirical laws to predict the evolution of the viscosity of a solution of acrylamide - acrylic acid copolymer. In fact, it appears... [Pg.125]

In a first part of this paper, we will discuss results of a 27A1 NMR study of the binding of Al ions on acrylamide-acrylic acid copolymers as a function of pH, at the light of a simple electrostatic model. The second part deals with the phase diagrams, physical gelation and precipitation phenomenon, for different copolymer compositions and under various conditions of concentrations, pH and salinity.

Lu et al. have reported that the fluorescence intensities of Eu3+ and Tb3+ are markedly enhanced when they are bound on to a poly(acrylamide-acrylic acid copolymer). Dhake et al. have observed interesting differential effects of pressure on the fluorescence of a polymer and the corresponding monomer. Sterically hindered piperidines have for long been of interest as efficient photostabilisers of polymers. Gugumus has now reported that these stabilisers form charge-transfer complexes with molecular oxygen, thereby preventing the formation of such complexes with the polymer. [Pg.577]

An LDPE model surface was coated with polyaminoxylene via chemical vapour deposition polymerisation. The functional surface was used to immobilise a polymeric drug release system consisting of isopropyl acrylamide-acrylic acid copolymer. The coupled drug release system was used to incorporate the thrombin inhibitor r-hirudin. 16 refs. [Pg.57]
