ABSTRACT:
A process to polymerize alkoxystyrenes utilizing a zeolite as the initiator is provided. Polymers of p-methoxystyrene having number average molecular weights in excess of 1.times.10.sup.6 are prepared by room temperature polymerization. The invention also provides a high molecular weight polymer of alkoxystyrenes which has a broad molecular weight distribution.
