Abstract A polyester plasticizer (RSOP) for polyvinyl chloride based on rubber seed oil (RSO) was synthesized. Firstly, RSO monoglyceride were synthesized by the transesterification of with glycerol at 220–240 °C. Secondly, RSOP from and adipic acid esterification. The characterized GPC, FT-IR, 1 H NMR DSC. Plasticized (PVC) materials dioctyl phthalate (DOP) in varying ratios prepared via therm...

Abstract Poly-L-lactic acid (PLLA) has been produced by ring-opening polymerization method. During the processes different temperatures and process times have applied to reach an optimum setup that was used produce sample. The sample measured Fourier-transform infrared spectroscopy (FTIR), gel permeation chromatography (GPC) differential scanning calorimetry (DSC) methods identify structure, mo...

Abstract The paper presents the results of research on influence used plasticizing system structural and thermal properties thermoplastic starch (TPS). granulate was obtained by extrusion native in presence a using twin-screw extruder. Glycerol urea were as plasticizers various proportions. In order to evaluate effectiveness plasticization process, changes its chemical structure analyzed infrar...

The recent studies on sustainable plasticizer mainly focus raw material source, synthesis method and plasticization, but the effect of chemical functional groups (epoxy group ester group) compatibility thermal stability plasticized polyvinyl chlorid (PVC) materials has been ignored. In this study, two kinds plasticizers (eleostearic acid eugenol (EAEE) epoxidized EAEE) were synthesized to plast...

Liquid -caprolactone (CL) oligomers were synthesized by a ring-opening reaction of CL using a propylene glycol (PPG) as the initiator for use as new plasticizers of poly (L-lactide) (PLA) films. PPG-CL oligomers containing two (PPG-2CL) and four (PPG-4CL) units of CL at both PPG end-chains were prepared. The PLA/oligomer blend films were prepared by solution blending before film casting. The t...
