ABSTRACT:
A method of preparing styrene derivative polymers is provided. The process utilizes as a catalyst an iodine containing electrophile and a zeolite. The styrene derivatives cationically polymerize to polymers without the need for heavy metal initiators. The styrene derivatives may be copolymerized with vinyl ethers to form random or block copolymers. Preferred styrene derivatives include styrene and methoxystyrenes.
