As diisocyanate has been selected toluene 2,4-diisocyanate (TDI) and as chain extender, 1,4-butanediol (BD).
The diisocyanate used in most of the experiments is a blocked isocyanate: toluene 2,4-diisocyanate dimer or di-TDI (Thanecure T9, Rhein Chemie).
Synthesis of the polyurethane: (Polymer-1) castor oil (55 g, 0.555 mole) was allowed to react with toluene 2,4-diisocyanate (TDI) (17.8 g, 0.099 mole) to maintain the NCO/OH ratio at 1.6.
