Complex liquids consisting of low-TG polymer-colloids: Structure and self-diffusion

Phase Equilibrium and Interdiffusion in Blends of Polystyrene with Polyacrylates

“…Among the numerous binary mixtures of polymers, the Polystyrene (PS)–Polyacrylates (PA) systems have been the subject of constant research for more than 30 years from the standpoint of the thermodynamics of components mixing, technological compatibility, peculiarities of their colloidal-chemical and adhesive properties, phase structure, and the structure of transition interphase layers [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. Nevertheless, information on the phase state diagrams of these systems, which is so necessary for the selection and substantiation of the composition and optimal supramolecular organization of this class of composite materials, adhesives, elements of transdermal systems, is fragmentary, contradictory, and insufficient.…”

“…Despite the fact that the statistical copolymers PBA and PS were among the first on which the method of labeled atoms was tested for the experimental evaluation of the self-diffusion coefficients of macromolecules [ 24 ], their translational mobility was practically not studied in the future. Only in works [ 4 , 6 , 10 ], with the use of NMR in a pulsed gradient and by the method of laser microinterferometry [ 20 , 22 ], was a comprehensive study of the diffusion and solubility of PSs of various molecular weights in block and gradient copolymers of n -butyl acrylate carried out, self-diffusion coefficients of PBA colloidal particles measured, the partial diffusion coefficients of PS macromolecules into the matrix of the copolymer of PBA and PS and of the copolymer into the matrix of PS determined, the coefficients of friction of macromolecules and monomer units calculated, and the activation energies of the translational mobility of macromolecules determined.…”

Functionalized polymer colloids bearing primary amino groups

“…During the last decades colloidal systems have been attracting considerable scientific interest both for fundamental and applied research [1][2][3], particularly due to the availability of nearly monodisperse nanoscale particles with the capability of self-organisation [4][5][6][7]. In aqueous suspension most of the systems are electrostatically stabilized [8][9][10].…”

Immobilized Highly Charged Colloidal Crystals: A New Route to Three-Dimensional Mesoscale Structured Materials

“…The monomer butylacrylate is commercially available and its emulsion polymerization provides highly charged and monodisperse particles. [18] Dynamic light scattering (DLS) experiments on these particles show that they have an average diameter of 200.5 nm (Figure 1) and are monodisperse; the geometrical Figure 1. Size distribution g(D) of polybutylacrylate colloids measured by DLS.…”

“…The monomer butylacrylate is commercially available and its emulsion polymerization provides highly charged and monodisperse particles. [18] Dynamic light scattering (DLS) experiments on these particles show that they have an average diameter of 200.5 nm ( Figure 1) and are monodisperse; the geometrical standard deviation of the logarithmic normal distribution of their sizes amounts to only s 1.08. The particles have a zeta potential of À 50 mV in the pH range of 6 to 10 due to the dissociation of surface-bound acid groups.…”
