Utilization of ricinoleic acid as a raw material for the synthesis of green plasticizer would offer an alternative to the phthalate plasticizers. Ester-amide of ricinoleic acid was synthesized by a two-step reaction with dibutyl amine and benzoic acid; and then utilized as primary plasticizer in PVC. Ester-amide plasticizer was added up to 40 phr in PVC; and the prepared PVC sheets were characterized for mechanical, X-ray diffraction, thermal, rheological, colorimetric, and exudation properties. Addition of the ester-amide plasticizer demonstrated good incorporation and plasticizing performance in PVC. Viscosity of PVC decreased with increased addition of ester-amide plasticizer. The dark color of the synthesized plasticizer could have constraints on its application areas; however, the prepared samples illustrated negligible weight loss in the exudation test, attributed to better compatibility between them brought about by the ester, tertiary amide and polarizable benzene ring in the ester-amide plasticizer with the C-Cl polar linkage in PVC.

“…Because of this, it is important to perform reliable weathering methods to test factors, like light and temperature, which influence the degradation of PVC based materials in accelerated service conditions. Due to the growing importance of the PVC, various studies have been reported that deal with the rheological behavior and mechanical properties of its blends [4], the properties of PVC/thermoplastic polyester elastomer blend systems [5], and fabrication of new antimicrobial PVC plastic [6]. The effect of UV light on the molecular structure of the PVC is an important issue that has attracted the attention of researchers [7].…”

Five new thiophenes, namely,N-[(3-bromo-2-methylthiophen-5-yl)methylene]-4-methoxyaniline (4a),N-[(3-bromo-2-methylthiophen-5-yl)methylene]-3,4-dimethoxyaniline (4b),N-[(3-bromo-2-methylthiophen-5-yl)methylene]-3,4-dimethylaniline (4c), 3-[(3-bromo-2-methylthiophen-5-yl)methyleneamino]-2-methylquinazolin-4(3H)-one (4d), and 3-[(3-bromo-2-methylthiophen-5-yl)methyleneamino]-2-isopropylquinazolin-4(3H)-one (4e), have been synthesized. All of these materials brought about a reduction in the level of photodegradation of poly(vinyl chloride) (PVC) films containing the synthesized thiophenes (0.5%; by weight). The results obtained showed that the extent of photostabilization of PVC in the presence of an additive was in the order4e > 4d > 4b > 4a > 4c. For the most favorable additive (4e), the rate of appearance of infrared absorption bands of degradation products was reduced by around two-thirds, while the quantum yield of chain scission was calculated to be reduced by a factor of more than one thousand. It is suggested that the additives may help stabilize PVC by direct absorption of UV radiation and dissipation of the energy as heat or that electrostatic attraction between the additives and PVC may assist transfer of energy from excited state PVC to the additive, from where it can be dissipated.

“…Similar results have been determined by Savadekar et al (2013) for nano-alumina added poly(butyleneadipate-co-terephthalate) composite films, again attributed to better interaction between them. Whereas, Kadam et al (2013a) demonstrated analogous behavior for nano-alumina reinforced poly (vinyl chloride)/thermoplastic polyester elastomer blend system. X-ray diffraction analysis X-ray diffractograms obtained for the prepared pristine guar gum and guar gum/alumina nano-composite films is demonstrated in Fig.…”

In this work, nano-alumina was utilized as a reinforcing agent for guar gum, with an aim to improve its performance properties; especially, mechanical and barrier i.e. water vapor transmission rate (WVTR). Films were prepared by the process of solution casting. Concentration of nano-alumina was varied as 0, 1, 3, 5 and 7 parts per hundred parts of resin (phr) in guar gum. The prepared pristine and guar gum/alumina nano-composite films were characterized for mechanical, puncture, x-ray diffraction, barrier, rheological and morphological properties. Tensile strength, Young's modulus, puncture strength, viscosity and crystallinity increased; whereas, WVTR, elongation at break (%) and damping factor decreased with increased concentration of nano-alumina in guar gum. However, optimized improvement in the performance properties were determined for 5 phr nano-alumina loaded guar gum polymer matrix, attributed to its better dispersion and interaction into the guar gum polymer chains due to the hydrophilic nature of both the materials. Above 5 phr concentration nano-alumina started forming aggregates, as evident from scanning electron microscopy.
