Pinene-derived diisocyanates

A pinene-derived diisocyanate compound, a process for forming a pinene-derived diisocyanate compound, and an article of manufacture containing a polyurethane polymer are disclosed. The process for forming the pinene-derived diisocyanate compound includes oxidizing the pinene to form a pinene-derived ketone compound, converting the pinene-derived ketone compound to a diamine compound in subsequent reaction steps, and reacting the diamine compound with phosgene to form the pinene-derived diisocyanate compound. The polyurethane polymer is synthesized in a reaction between a pinene-derived diisocyanate compound and a polyol.
