520			_aNatural rubber (NR) on chlorination turns into a white thermoplastic material which is widely used by the paint and lacquer industries taking advantage of its improved ageing properties, flame retardance, adhesion to various substrates etc. A major impediment in the manufacture of chlorinated natural rubber is the gel content of raw NR which makes preparation of solution difficult. In this study this problem has been solved to a great extent by using depolymerised liquid natural rubber (LNR). Substantially higher amounts (upto 20;) of LNR could be dissolved in carbontetrachloride to obtain a liquid mass that could be stirred and homogenized during the course of chlorination. This has resulted in manifold increase in the output compared to conventional method of chlorination of NR solution. Prperties of the product have been found comparable with chlorinated rubber prepared from raw NR.
