Polyphosphates as Inhibitors for Poly(vinyl Chloride) Photodegradation
Molecules, 2017 Three polyphosphates were used as inhibitors for poly(vinyl chloride) (PVC) photodegradation. The polyphosphates were added to PVC at a concentration of 0.5% by weight. The PVC films (40 µm thickness) were irradiated at room temperature with ultraviolet (
