“…When it comes to their thermal stability, they are deemed stable at room temperature, while they are being decomposed at temperatures above 200 °C with liberation of NO. [23][24][25][26] Depending on the structure of the initial molecule and thermolysis conditions, thermolysate may contain compounds that are the results of decomposition of the initial material and/or compounds formed by the decomposition or recombination of fragments formed from the initial compounds. [13][14][15][16][17][18] Methyl N-methylanthranilate is a part of our everyday diet as it naturally occurs in various fruits and plants and is used as a food flavor.…”

“…The band located at 1576 cm -1 was observed both in curve B and curve C, which belongs to the characteristic peak of aromatic ring [33] and was not observed in cotton fabrics. The band at 1709 cm -1 is ascribed to the stretching vibration of C=O group in BTCA and hydantoin diol molecules.…”

Cotton fabrics have received more and more attentions due to their excellent properties such as hygroscopicity and comfortability. However, cotton fabrics also have some disadvantages such as easiness to wrinkle, poor ultraviolet resistance, and breeding bacteria. In this work, we used (3-(2,3-dihydroxypropyl)-5,5-dimethylimidazolidine-2,4-dione (abbreviated as hydantoin diol) and 2,4-dihydroxy diphenylketone (abbreviated as UV-O) as antibacterial agent and ultraviolet absorber, respectively. They were bonded to cotton fabrics with cross-linking agent 1,2,3,4-butanetetracarboxylic acid (BTCA) using the pad-dry-cure process to achieve multi-function by one step. The hydantoin diol/UV-O treated cotton fabrics were characterized by SEM and FT-IR. The UPF of the cotton increased from 4 to 36 and the wrinkle recovery angle increased from 112 o to 169 o after treatment. The addition of 2,4-dihydroxy diphenylketone could also improve the UV stability of NCl bonds on the coated cotton. The chlorinated hydantoin diol/UV-O cotton could inactivate 1.05×10 6 CFU/sample of S. aureus and 2.2×10 6 CFU/sample of E. coli O157:H7 with 5 min of contact completely.

Electron beam (E-beam) curing by different total radiation doses (100, 200, 300 and 400 kGy at 10 kGy per pass) of functionalized maleimides (20%) [ N-(4-acryloyloxy phenyl)maleimide, N-(4-methacryloyloxy phenyl)maleimide and N-(4-cyanato phenyl)maleimide] is carried out using N-vinyl-2-pyrrolidone as the reactive diluent (80%). The swelling studies indicate the presence of highly cross-linked structure in the polymer derived from cyanate-functionalized maleimide cured using 400 kGy electron beam (E-beam) irradiation. The thermal stabilities of all the polymers are studied using thermogravimetric analyzer. The materials cured using the highest radiation dose (400 kGy) are found to have better thermal stability compared to other materials cured using lower doses (100, 200 and 300 kGy at 10 kGy per pass). The degradation kinetic studies using the Vyazovkin method showed that the activation energies for the thermal degradation of polymeric materials got by E-beam irradiation of the monomers at 400 kGy are higher. Of all the materials investigated, liquid composition having N-(4-cyanato phenyl)maleimide (20%) and N-vinyl-2-pyrrolidone (80%) cured by E-beam radiation (400 kGy) showed better thermal stability.
