Performance assessment of polyvinyl chloride films plasticized with Citrullus lanatus seed oil based novel plasticizer

Polymer Testing, 2021
Biobased plasticizers for polymers is a necessity to replace conventional phthalates based plasticizers. In the present study, Citrullus lanatusseed oil (ECLO) was epoxidized in a magnetically stirred reactor.

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 (

New Tetra-Schiff Bases as Efficient Photostabilizers for Poly(vinyl chloride)

Molecules, 2017
Three new tetra-Schiff bases were synthesized and characterized to be used as photostabilizers for poly(vinyl chloride) (PVC) films. The photostability of PVC films (40 μm thickness) in the presence of Schiff bases (0.5 wt %) upon irradiation (300 h ...

Production of PVC-films with specific properties

Nanotechnologies in Construction: A Scientific Internet-Journal, 2018
When developing polymeric materials with specified properties special compounds such as fungicides are used alongside traditional chemical additives (plasticizers). Usage of fungicides are determined by negative influence of mold fungi, bacteria and other microorganisms on polyvinyl chloride (PVC) material.
