Balakrishnan, Remya; Nallaperumal, Agasthiyalingom Meenakshi; Manu, Saraswathy Kesava Pillai; Varghese, Lity Alen; Sekkar, Venkataraman published the artcile< DSC assisted kinetic analysis on the urethane network formation between castor oil based ester polyol and poly(methylene di phenyl isocyanate) (pMDI)>, Electric Literature of 112-63-0, the main research area is castor oil polyol pMDI urethane network formation kinetics.
Kinetics of the reaction between castor oil based ester polyol (CEP) and poly(methylene di Ph isocyanate) (pMDI) was studied adopting differential scanning calorimetry (DSC). DSC scans were recorded at various heating rates, viz.: 5, 10, 15 and 20 K.min-1. Hydroxyl and isocyanato compounds were taken at stoichiometric ratio [r=[NCO/OH]=1] Both single heating rate methods (Coats-Redfern, Chatterjee-Conrad) and multiple heating rate based iso-conversional methods (Ozawa, Freidman and Kissinger) were adopted to calculate the kinetic parameters. DSC thermograms consist of two exothermic peaks at temperatures 343 and 393 K, for all heating rates. Kinetic parameters were calculated using input parameters deduced from DSC thermogram. The reaction was assumed to be second order and the corresponding second order equations were applied for evaluating the kinetic parameters.
International Journal of Polymer Analysis and Characterization published new progress about Activation energy. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Electric Literature of 112-63-0.
