Synthesis and evaluation of N,N-dibutylundecenamide as new eco-friendly plasticizer for polyvinyl chloride

Tertiary fatty amide, namely N,N-dibutylundecenamide (DBUA), has been synthesized and evaluated as potential plasticizer for polyvinyl chloride (PVC). Homogeneous PVC/DBUA composite films containing 20, 30 40 wt% of DBUA were prepared by solvent casting. Infrared analysis blends indicated molecular interactions between polar –CH–Cl group PVC carbonyl tertiary amide. According to results mechanical testing, 40% have significantly increased elasticity with reduced Young’s modulus over 90%, well elongation at break approximately 130% compared neat polymer. Good plasticizing efficacy toward also revealed differential scanning calorimetry analysis. Thus, the introduction (20% 30%) into its glass transition temperature 64.8 91.4 °C, respectively. The thermal gravimetric stability PVC, polymer compositions common bis(2-ethylhexyl)phthalate (BEHP). However, degradation point plasticized material (217 ºC) still remained higher than actual processing methods. was found volatility, but better resistance migration from films, PVC/BEHP blends. biodegradability determined primary biodegradation test CEC L-33-A93 be 92.6% after 21 days. Overall, obtained indicate that amide is promising eco-friendly which combines good low-temperature performance, high biodegradability, matrix.
