Electrophysical Properties Of Polymers With Implanted Amorphous Single Component Metals R.Malkhasyan,R. Krmoyan, V.Kosyan. Scientific – Production Enterprise “ATOM” Yerevan, Republic of ARMENIA. ABSTRACT For the last years, especially after the creation of conducting polymers, much prominence has been given to the works on creation and working out the new technologies of implantation of different metals and, on the whole, inorganic components into the structure of different polymers. Of special interest are rapidly developing researches in the field of creation and application of different nanomaterials also including metals in the processes of synthesis of different polymers. The data on electrophysical properties of polyvinyl acetate with doping amorphous molybdenum, obtained for the first time in SPE “ATOM” of Armenia, are being presented and discussed for the first time in the given paper. It is shown, that the dopes of amorphous nanosize molybdenum and crystalline nanosize molybdenum in the process of polymerization lead to its implantation into the structure of polymer. Amorphous molybdenum practically always lowers substantially electrical resistance of composite materials. INTRODUCTION Polymers with the different fillers for the purpose of creation of composite materials with the given properties are very actual, sufficiently studied field [1-3]. There are also researches on application of amorphous metallic alloys in the processes of synthesis of different polymeric composite materials [4-5]. Lately, in connection with creation of new class of nanosize crystalline materials, the intensive searches of the fields of their application including also polymerization processes are started [6-7]. Taking into consideration that the principal physico-chemical properties of nanosize materials also including metals differ substantially from analogous bulk materials and also depend on the size of the grains themselves, one may expect a lot of new interesting data in the near future. The main expectations by using nanosize metals as other materials too are connected with their additional Grain Boundary Energy of nanosize particles. In this connection for the first time synthesized by us in SPE “ATOM” of Armenia new nanosize amorphous metals (not alloys) are of special interest [8-10]. The given metals are exclusively active materials , as all amorphous materials and as all nanosize materials, and therefore as if they have double energy saturation that just becomes apparent in different fields of their application, for example, as catalysts etc.[11-12].

EXPERIMENTAL The process of polymerization of vinylacetate monomer in ethanol solution with the initiator of dinytrile of azoiso oil acid (DAA) in a quantity of 0,4% was investigated. Polymerization was carried out at the temperature 60 – 70 0C within 150 – 350 minutes. The experiments were conducted on a doubled lab installation consisting of two glass reactors with capacity of 1 liter, provided with mixing devices and placed in one and the same bath
