“…20,21,23 The absorption band at about 1727 cm −1 is the C O characteristic peak of carboxyl groups, which originate from the vinyl acetate units in the acrylonitrile copolymer. 36 The FTIR spectrum of the PAN-g-GMA fabric shows some new typical peaks. Absorption bands appear at 1727 cm −1 and 1150 cm −1 , arising from C O and C O C (epoxide) stretching vibrations, respectively.…”

A novel flame‐retardant polyacrylonitrile (PAN) fabric was successfully prepared by ultraviolet‐induced grafting polymerization of glycidyl methacrylate (GMA) onto the surface of PAN fabric (PAN‐g‐GMA) followed by ammoniation and phosphorylation. The effects of irradiation time, initiator concentration, and monomer concentration on the grafting percentage were researched. Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy, and scanning electron microscopy indicated the successful modification. Thermal behaviors of the samples were studied by thermogravimetric and derivative thermogravimetric analysis. The results indicate that the fire‐retardant PAN fabric (FR‐PAN) has good char‐forming ability. Cone calorimeter tests showed that the total heat release of FR‐PAN decreased from 7.3 MJ/m2 to 4.6 MJ/m2 with 37% reduction. At the same time, the peak of heat release rate of FR‐PAN fell from 374 kW/m2 to 162 kW/m2 with 57% decrease. Moreover, the total smoke production and peak of smoke production rate of FR‐PAN dropped from 1.5 m2 and 0.06 m2/s for the control sample to 0.4 m2 and 0.03 m2/s, respectively. The limiting oxygen index value of FR‐PAN fabric was 30.7% after 30 washing cycles, indicating good washing resistance and excellent flame‐retardant durability. © 2018 Wiley Periodicals, Inc. J.

“…El uso de enzimas en reacciones de injerto ha sido extensamente estudiado en mayor proporción en biopolímeros que para polímeros sintéticos. [45,46]. Entre las principales características de este tipo de injerto se encuentran: i) el injerto ocurre en condiciones suaves de reacción y usualmente no se requiere el uso de materiales peligrosos, ii) la etapa de iniciación requiere de la enzima para formar los radicales libres, iii) la selectividad de la enzima hace que la reacción sea simple y ofrece un mejor control sobre la estructura macromolecular.…”
