Knowhow offering
Title	Value added chemicals from Cashew Nut Shell Liquid(CNSL)
Knowhow is available for	Specialty monomers and polymers from CNSL that have wide ranging industrial and consumer applications
Summary	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 CSIR-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.
Advantages	-High performance polymers produced from CNSL have improved processability -Produced from low cost raw materials that are widely available in India -Possibility of significant value addition on CNSL -Sustainable, renewable raw material source
