ABSTRACT:
Method and apparatus for the chlorination of polyolefins in aqueous suspension. The method includes subjecting the suspension of the polyolefin to a submerged jet of chlorine gas at a velocity sufficient to atomize the chlorine; i.e., at least about sixty feet per second. By this method a very intimate mixture of chlorine and aqueous suspension is formed, whereby the chlorination proceeds more efficiently and at a lower chlorine pressure. Further advantages include a more uniformly-substituted product.
