In this paper samples of poly vinyl chloride PVC ,pure, irradiated
with Gama rays, were prepared by casting method in room
temperature and light, and under atmosphere pressure.
It was observed from this research that irradiation made real effect
on some of the studied optical properties, the irradiation increased
the transmittance while the electronic transitions kind remained
indirect before and after the irradiation.
The pollution is one of the most important problems facing the
electrical networks, especially in the Syrian Arab Republic, and
after that expanded of pollution sources on the one hand, and
because the power supply has become related to all economic
and daily life sections.
The molecular weight (Mw, Mv) variations according to Cole - Cole
representations were studied by applying variable temperature degrees,
dynamic frequencies on a number of polymers: polypropylene (PP) isotactic,
polybutene (PB), polyamide-١٢ (PA-١٢), high density polyethylene (HDPE).
