Modification of polyvinyl chloride with Na(K) salts of 1,2,4-triazole and 1,2,3-benzotriazole

Synthesis, dielectric and magnetic characteristics of poly(1-vinyl-1,2,4-triazole) (PVTri)–barium hexaferrite composite

“…[25]. As conducting polymer, poly(1-vinyl-1,2,4-triazole) is readily soluble in H 2 O and DMSO, nontoxic (LD 50 > 3000 mg/kg), biocompatible, thermally stable, and has a controllable molecular weight (10 4 to 10 6 Da) [26,27].…”

“…Fig. (1) demonstrates the variety of ln(At -A ∞) with irradiation time for all added substances in poly(vinyl chloride) chips at the wavelength 365nm.…”

“…The absorption spectrum was measured in the range of ( max = 200-400) nm . The photodegradation rate constant for photostabilizer )k d ( calculated using the first order kinetic equation, ln(a-x) = ln a -k d t ......... (1) Where: a : represents the stabilizer concentration before irradiation.…”

Photostability Study of Some Modified Poly(vinyl chloride) Containing Pendant Schiff’s Bases

“…Poly(vinyl chloride), better known by its abbreviation (PVC), is one of the most significant polymers due to its competent properties, the growth of the Polyvinyl chloride production is due to the stable expansion of its application fields [1]. Poly(vinyl chloride) is known from poor thermal and light stability.…”
