“…As it is clear, it has been occurred some little changes in the morphology of the fiber but photographs demonstrated that the surface of 17.46 % poly AA-grafted acrylic fiber was as smooth and homogeneous as that of pure fiber. This can be related to lower grafting yield due to the chemically and physically bonded poly AA on the fiber [20].…”

The graft copolymerization of acrylic acid (AA) onto commercial acrylic fibers (PAN) has been studied using Azobis(isobutyro)nitrile (AIBN) as an initiator. AA grafting initiated by radicals formed from thermal decomposition of AIBN. In this study, the effects of monomer and initiator concentration, time and temperature reaction on the grafting yield have been investigated.The optimum conditions for this grafting reaction were obtained with an AA concentration of 1.67 M, an AIBN concentration of 0.0097 M, a reaction temperature of T=85 C and with reaction time of 60 minutes.The fiber structure has been investigated by different experimental techniques of characterization such as Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), water absorption and also in this study has been investigated the mechanical property. The thermal analysis data showed that increasing in grafting yield, decreases the thermal stability of fiber. Grafting also affected slightly the fiber morphology. The experimental data of mechanical properties show clearly that by increasing of grafting yield, max extension will decrease. Grafting of poly AA improved water absorption.

A monolithic imprinted atenolol column was constructed by in situ polymerisation using a methacrylic acid monomer and a 1 : 1 (v/v) porogen of propanol: toluene with two template: monomer: crosslinker combinations, namely, MIP 1 (1 : 4 : 20) and MIP 2 (1 : 5 : 20). Physical characterisation of the monolithic columns consisted of permeability testing, Fourier transform infrared (FTIR) testing, surface area analysis (SAA), and scanning electron microscopy (SEM). The permeability value of four monolithic columns was in the good category: MIP 1 (24.01 mD), NIP 1 (56.43 mD), MIP 2 (23.03 mD), and NIP 2 (14.47 mD). The polymerisation process of these four monolithic imprinted columns was carried out perfectly, as shown by the absence of vinyl groups (1000 cm−1 and 900 cm−1) during FTIR testing. Based on SAA testing, the pores of the four polymers were classified as mesopores. The best monolithic column was MIP 1, as seen from the intercolumn and intracolumn reproducibility values and a % RSD <2.0%. The MIP 1 column was selective towards atenolol, as seen from the selectivity factor, imprinting factor (IF), and resolution (Rs) values. The IF values of MIP 1 were atenolol (204.62), metoprolol (3.36), and propranolol (1.27). The Rs value between atenolol and the analogue compounds was 7.23. The MIP 1 column can be used for the analysis of atenolol in blood serum samples with an average percentage recovery rate of 94.88 ± 4.43%.

“…2-thiozyl methacrylamide (TMAAm) is one of the most important vinyl monomers for large polymer-addon can be easily obtained because of the hydrophilic natüre of the TMAAm [53,54]. Poly(2-thiozyl methacrylamide), as an important industrial polymer, has some desirable properties, including, it is less toxic, polar and less expensive than other vinyl monomers [55].…”

The aim of this work is the preparation and properties of poly 2-thiozyl methacrylamidevinylbenzyldimethyloctadecylammonium/montmorillonite (TMAAm-VBOA/MMT) nanocomposites. Firstly 2-thiozyl methacrylamide (TMAAm) monomer was synthesized by reacting 2-amino thiazole with methacryloyl chloride in the presence of triethylamine. Synthesis of nanocomposites were performed in three steps which are; purification and cation exchange capacity (CEC) determination of clay, preparation of organoclay and synthesis of nanocomposites. Nanocomposites with various amounts of TMAAm and VBOA/MMT were synthesized through in-situ and free radical polymerization using benzoyl peroxide as an initiator. Changes in the structure of the nanocomposites were examined through Fourier transform infrared spectroscopy (FT-IR), X-ray diffractometry (XRD) and scanning electron microscopy (SEM). Additionally, thermogravimetric analysis and BET analysis were conducted to investigate the thermal properties and particle size distribution of the nanocomposites. The results of X-ray and SEM analysis suggest that the exfoliated structure of the new nanocomposite materials. In addition, the thermal decomposition temperatures of nanocomposites were found to be higher than that of pure organoclay and poly(TMAAm) and thermally degradation rate decreased.
