Formation of silver nanoparticles into nonionic polymer matrices of various molecular structure.

Branched copolymers dextran-polyacrylamide and linear polyacrylamide were obtained using radical polymerization method. Their molecular parameters were determined and the ability to use them as matrices for in situ synthesis of silver nanoparticles it was shown. The factors allow to obtain the stable silver colloids with narrow distribution in size were established. The temperature increasing leads to silver nanoparticles formation bigger in size and with wider polydispesity. Nanopsystem formation observes at high temperature only in branched polymer matrices.
