Value-added Chemicals from Cashew Nut Shell Liquid
A range of difunctional monomers (dihalides, diacids, diisocyanates, diamines, diacyl hydrazides, diphenols, dialdehydes etc.) and polymer additives are produced utilizing 3- pendadecyl phenol derived from cashew nut shell liquid (CNSL) using NCL’s technology. A host of high-performance polymers (polyimides, polyamides, polyesters, poly(amide-imide)s etc.) can be prepared using the difunctional monomers mentioned above.
