“…moiety as pendent group to a polymer backbone has been attempted to get some uses by free radical polymerization or macromolecular reactions. [14][15][16][17] Poly(N-isopropylacrylamide) (PNIPAAm) is one of the well-known thermo-responsive polymers. It exhibits a lower critical solution temperature (LCST) in aqueous media, below which the polymers are water-soluble and above which they become significantly less water-soluble or water-insoluble.…”

Summary: Novel hydrophobic comonomer (p‐methacrylamido)acetophenone thiosemicarbazone was synthesized and polymerized with N‐isopropylacrylamide to get a series of amphiphilic copolymers. The self‐aggregation behavior and thermo‐sensitive character of the (co)polymers were confirmed by TEM observation, fluorescence spectra, and cloud point measurement. Fluorescence emission of copolymer was significantly strengthened or switched off at an excitation wavelength of 320 nm upon the addition of acid or base, respectively. Thermo‐sensitivity, pH‐sensitivity, and pharmacologically versatile thiosemicarbazone groups were integrated into these novel fluorescent and amphiphilic copolymers, which will develop the novel applications of amphiphilic copolymer and environment‐responsive materials.

Tetra-aldehyde and ketone derivatives (2a-d) which were used to obtain tetra thiosemicarbazone compounds 3a-h were synthesized via the reaction of Ethene-1,1,2,2,-tetra-yl-tetra-methylenetetra-bromide (1) with aldehydes and ketons. Then, tetra-thiosemicarbazone compounds 3a-h were obtained from the reactions of tetra-aldehyde and keton derivatives (2a-d) with thiosemicarbazite and 4-methyl thiosemicarbazite, respectively. In the same way, tetra-4-methyl-5-ethoxycarbonyl-2,3-dihydro-1,3-thiazole compounds 4a-h were synthesized via the reaction of tetra-thiosemicarbazone compounds 3a-h with ethyl-2-chloroacetoacetate. Then, tetrathiosemicarbazone compounds 3a-h were reacted with acetic anhydride, and yielded tetra-2-acetyl-amino-4-acetyl-4,5-dihydro-1,3,4-thiodiazol compounds (5a,b,c,e,f,g). They were characterized by elemental analysis, infrared, 1 H and 13 C-NMR, mass spectroscopy. Then, the microbial features of all compounds were studied by the known method.

“…The oxime, carbazone, and thiosemicarbazone derivatives of N (4-acetylphenyl) maleimide were radical homopolymerized and the polymer obtained shows good antimicrobial activity [24]. Patel et al [25] prepared furan resins derived from o-cresol and furfural under various reaction conditions by a polycondensation technique.…”

A copolymer resin, p-chloroacetophenone oxime-furfuraldehyde (CAOFU), and a terpolymer resin, p-chloroacetophenone oxime-formaldehyde-benzoic acid (CAOFUBA), were synthesized in the presence of hydrochloric acid as catalyst. The structures of copolymer and terpolymer were established by FT-IR and 1 H NMR techniques. Molecular weight and polydispersity index were determined by gel permeation chromatography. The thermal stability was evaluated by thermogravimetric analyses (TGA). Softening temperatures (T s ) of these polymers were obtained from differential scanning calorimetry (DSC). All the synthesized polymers have shown reasonably good antimicrobial activities.
