Abstract
The effects of molecular mass of polyacrylic acid on the degree of binding of silver cations and the dimensions of nanoparticles produced by the photo chemical reduction of the resulting complex were studied. It was shown that , in the presence of polyacid with M = 4.5 x 10(5), monodisperse spherical nanoparticles 1-2 nm in diameter are formed. As the molecular mass of polya cid decreases to 2 x 10(3), the coarse polydisperse particles with diameter up to 20 nm are produced.
