Biobased polymer has taken tremendous attention in recent times. In the present study bio-based polyurethane have been synthesized from the vegetable oil i.e., dehydrated castor oil, 1,4-butanediol and isophorone diisocyanate in presence of a catalyst by solution polymerization method. Then polyurethane nanocomposites were synthesized using...

Preparation and Characterization of Controlled-Release Avermectin/Castor Oil-Based Polyurethane...

Avermectin (AVM) is a low-toxic and high-active biopesticide, but it can be easily degraded by UV light. In this paper, biodegradable castor oil-based polyurethanes (CO-PU) are synthesized and used as carriers to fabricate a new kind of AVM/CO-PU nanoemulsion through an emulsion solvent evaporation method, and the chemical structure, colloidal...

Physical properties and morphology of crosslinked polyurethane synthesized from para‐phenylene...

A series of crosslinked polyurethanes (PUs) were synthesized from para-phenylene diisocyanate, 2-(hydroxymethyl)-2-ethyl propane-1,3-diol (TMP), and butane-1,4-diol as the hard segments and poly(oxytetramethylene glycol) as the soft segments. The effects of TMP on the physical properties and microphase structure of the PUs were studied with dynamic...

Influence of Diisocyanate, Glycidol and Polyol Molar ratios on the Mechanical and Thermal properties...

A series of epoxy-terminated polyurethanes (EPUs) were synthesized from castor oil, 4,4′-methylenebis(cyclohexyl isocyanate) (H12MDI) and 2,3-epoxy-1-propanol (glycidol) by changing the molar ratio of H12MDI to glycidol to polyol. Fourier transform infrared, 1H NMR and solid-state CP/MAS 13C NMR spectroscopic analyses revealed the presence of...
