In order to find out the shift of ductile nature of acrylonitrile-butadiene-styrene (ABS) polymer to brittle nature while maleic anhydride (MA) grafting, the iodine value of different MA-grafted ABS (MA-g-ABS) sampled has been determined. The iodine value of thermoplastic polymer is found by Wijs method with slight modification to overcome the poor solubility of thermoplastics in tetrachloromethane. Different samples with varying MA content were prepared using internal mixer. All the specimens were characterized by attenuated total reflectance IR spectroscopy and X-ray diffraction analysis. The iodine value measurements revealed that grafting and cross-linking evidently reduced the unsaturation in ABS polymer matrix. The grafting of MA causes the decrease in impact strength, flexural modulus, and a significant increase in crystallinity, tensile strength, yield point, and flexural strength, whereas thermal stability remains intact. Field emission scanning electron microscope images showed noticeable difference in broken surface texture between ABS and grafted samples.

“…Such compounds have been used in commercial applications [11][12][13][14] especially in liquid-crystal and fire-retardant materials, where it has Molecules 2020, 25, 2122 2 of 26 been proved that phosphazene-based compounds exhibit effective flame-retardant properties [15]. Jae Shin et al (2010) reported the application of cyclotriphosphazene derivatives as fire retardants [16]. Phosphorus-based materials are thermally quite stable and versatile in their fire-retardant activity.…”

Liquid-Crystal and Fire-Retardant Properties of New Hexasubstituted Cyclotriphosphazene Compounds with Two Schiff Base Linking Units

A series of new hexasubstituted cyclotriphosphazene compounds (4a–j) consisting of two Schiff base linking units and different terminal substituents was successfully synthesized and characterized. The structures of these compounds were confirmed using Fourier Transform Infra-Red (FTIR), Nuclear Magnetic Resonance (NMR), and CHN elemental analysis. Polarized optical microscopy (POM) was used to determine their liquid-crystal behavior, which was then further confirmed using differential scanning calorimetry (DSC). Compounds 4a–i with heptyl, nonyl, decyl, dodecyl, tetradecyl, hydroxy, 4-carboxyphenyl, chloro, and nitro terminal ends, respectively, showed the liquid-crystal properties, whereas compound 4j with the amino group was found to be non-mesogenic. The attachment of an electron-donating group in 4j eventually give a non-mesogenic product. The study of the fire-retardant properties of these compounds was done using the limiting oxygen index (LOI). In this study, polyester resin (PE) was used as a matrix for moulding, and the LOI value of pure PE was 22.53%. The LOI value increased to 24.71% when PE was incorporated with 1 wt.% of hexachlorocyclotriphosphazene (HCCP), thus indicating that HCCP has a good fire-retardant properties. The result showed that all the compounds have good agreement in their LOI values. Compound 4i with a nitro terminal group gave the highest LOI value of 28.37%.

“…When organic groups are bonded at each phosphorus atom, the phosphazene skeleton is stabilized against hydrolytic attack [1,5]. The phosphazenes, particularly the substituted phosphazene derivatives containing organic or inorganic side groups, have generated considerable research interest in recent years because of their unusual physical and chemical properties such as organic light emitting diodes and fluorescence sensor [6][7][8], cathode material for rechargeable lithium batteries [9] and flame retardants [10].…”
