Biobased diisocyanates are derived from 3-petadecyl phenol, which is derived from Cardanol harvested from cashew nutshell liquid food waste. The biobased diisocyanates are of the formulas:

##STR00001##

wherein R is an alkyl chain C.sub.15H.sub.31 (n-pentadecyl); R.sub.1═CH.sub.3 or COCH.sub.3; and R.sub.2 is an alkylene of from about 1 to 18 carbon atoms.
