dc.description.abstractA new kind of polybenzoylthiourea polymer (PBTU) was synthesized through a polycondensation reaction between 3,5-diamino-1,2,4-triazole and tereftaloyl diisothiocyanate in poly(ethyleneglycol)dimethylether (PEG) as the phase transfer catalyst. Obtained polymer was highly soluble in organic solvents including N,N-dimethyl formamide (DMF) and dimethyl sulfoxide (DMSO) in contrast to the insoluble nature of similar benzoyl thiourea polymers reported in the literature. Solubility of the obtained polymer allowed us to measure the molecular weight of the obtained samples by gel permeation chromatography (GPC) analysis. GPC analysis results interestingly showed bimodal molecular weight distribution probably due to the oligomeric PEG residuals during the workup procedure. Structure of the obtained polymer was characterized by 1H NMR, 13C NMR and elemental analysis. The glass transition temperature (Tg) and the melting temperature (Tm) of the polymer was observed at 229oC and 304oC, respectively. Total pore volume and surface area of the polymer were calculated as 0.292 cm3 /g and 17.773 m²/g, respectively. Hardness and elastic modulus of the obtained PBTU capsule were measured respectively as 2.353 GPa and 0.136 GPa using nanoindentation technique.en_US
