Abstract
Modified chlorinated polyolefins obtained by heating the chlorinated polyolefin with a hydrocarbon acid having at least 7 carbon atoms in the presence of a free radical initiator are disclosed. The modified chlorinated polyolefins can be formulated into aqueous dispersions and coated onto plastic substrates to improve the adhesion of subsequently applied coatings.
