X-ray investigations of crystalline phase in polyethilentereftalat supermolecular structure influenced by the thermal, radiation and magnetic effects

The temperature dependence of the polyethilentereftalat supermolecular structure is investigated. It is shown that the most crystalline phase is formed at $80^\circ$C temperature ($1 h$) inlike the literature data, according to which the most crystalline phase is formed at $110^\circ$C. Crystalline formations size $10^{-5} $cm are formed in polyethilentereftalat at the magnetic field influence. $\alpha$- and $\gamma$-radiation influences destroy the crystalline phase and increase the amorphous phase.
