Nylon is a  polymer with a wide spectrum of industrial applications.It is generally available in different grades depending on the nature of monomeric constituents of which Nylon6,10 and Nylon 11 are of special attention as their constituents are derived from castor oil.

Nylon 11 is a modern day polymer first produced by Arkema,France in 2009 by utilizing a castor oil derivative, aminoundecanoic acid which is unique to serve as a reactant for polymer synthesis by self-polycondensation. According to the firm,they commercialized the product as Rilsan and claims that the technology is accessed by firms Japan’ Unitika and Monnet and Sofila of France and proved to be satisfactory.They further claim that the products generated from Nylon 11 are dimensional stability, abrasion and thermal resistance etc.

In spite of its advantages,sources say that the yarns seem to be expensive and non biodegradable which may tend to raise the environmental and industrial concerns over the large and long range application of this wonderful polymer
