“…Pure PS was investigated first since it was not clear if the ethylene diamine would react with the acrylonitrile. [77] An oligomer was used to get a better resolution for characterizing the end group of the polymer. It was attempted to verify this reaction by proton nuclear magnetic resonance spectroscopy ( 1 H NMR).…”

Styrene/acrylonitrile (SAN) copolymers with excellent chain-end fidelity and low polydispersity M w /M n (1.10 -1.30) were synthesized by nitroxide mediated polymerization (NMP) in dimethylformamide (DMF) solution with a succinimidyl ester (NHS) terminal group from the so-called SG1 nitroxide residue. These copolymers were thermally stabilized by removing the N-tertbutyl-N-[1-diethylphosphono-(2,2-dimethylpropyl) nitroxide] (SG1), and then modified to form primary amine end-functional SAN (SAN-NH 2 ). Homogeneous coupling reactions and Fourier-transform infrared spectroscopy (FTIR) indicated that the amine group was effectively placed at the chain end. SAN-NH 2 was reactively blended with maleic anhydride grafted poly(ethylene) (PE) at 20 wt.% loading at 180 °C and the resulting morphology was compared against the nonreactive blend. Scanning electron microscopy (SEM) indicated finer SAN domains ~ 1 μm which were thermally stable upon annealing in the reactive case.The dispersed SAN domains were reoriented using a channel die to impart elongated domains with aspect ratios ~ 14, which would be desirable for barrier materials.ii iii

“…However, the products of PAN with ethanolamine and with ethylenediamine were soluble in water depending on the amine‐nitrile group ratio. Todorov et al investigated the effect of reaction condition for obtaining maximum conversion of amino groups . They identified that the optimum condition for the reaction of nitrile group with ethylene diamine (AN: EDA, 1:5 ratio) is at 120°C for 2 hr.…”

The physicochemical properties of polymers are mainly dependent on the nature of polymer backbone and/or pendant groups linked to the main chain. Therefore, synthetic modification of these functional groups via post functionalization is an important approach for obtaining novel polymeric systems with improved properties and targeted applications. In this context, the synthetic modifications of nitrile group in polymers into various useful functionalities have received considerable attention and several interesting applications of the resulting polymers have been identified. The majority of the studies are based on Polyacrylonitrile (PAN), and some isolated examples of nitrile functionalization in copolymers such as Poly (Styrene-co-Acrylonitrile) (SAN), Poly (Acrylonitrile-co-Butadiene-co-Styrene (ABS) and Nitrile Rubber (NBR) are available. These synthetic modifications are mainly accomplished by the reactions such as Nucleophilic addition, cycloaddition, reduction, and hydrolysis using various reagents. These studies describing the post-polymerization modifications of nitrile group in polymers reported during the last three decades are covered in this review.

“…An increased hydrophilicity would enhance comfort to wear since sweat could penetrate and evaporate and static cling and stain retention during laundering would be reduced (Guebitz & Cavaco-Paulo 2008). The ability of a fibre to adsorb or to covalently bind dyes has, traditionally, been improved and enhanced by physical or chemical methods (Bendak 1991;Todorov & Valkov 1996;Makhlouf et al 2007), which have recently been complemented by plasma and laser surface modification techniques (Wong et al 2000;Ferrero 2003) or UV radiation methods (Lipp-Symonowicz & Sztajnowski 2003). However, most of the classic methods are, to some extent, environmentally harmful and/or rather complex when it comes to their technological application to the fibres (Battistel et al 2001).…”
