<p>A method of making an organic solution of a chlorinated polyolefin that produces a storage-stable solution, a chlorinated polyolefin resin is dissolved in a hydrocarbon solvent that is predominantly aliphatic hydrocarbon, aromatic hydrocarbons other than toluene and xylene, or mixtures of these, held at a temperature from 118 to 125 C, for an adequate time for complete dissolution, then cooled and a cosolvent is added at a temperature below the boiling point of the cosolvent but at a temperature at which the chlorinated polyolefin solution is still clear or has little haziness. The solution can be used to prepare coatings, primers, inks, and adhesives, particularly for plastic substrates such as thermoplastic polyolefin.</p> |
