ABSTRACT:
Vinyl ether copolymers and a method of preparing the same. The vinyl ether is copolymerized with styrene, alkyl-substituted styrenes, alkoxy-substituted styrenes and mixtures thereof. In the process, a cadmium halide is used with hydrogen iodide or a suitable iodine containing electrophile, as the coinitiator.
