Suspension polymerization of polystyrene

Abstract

Commercially relevant polymers are manufactured on a multi-ton scale before pelletization for use in injection molding applications.? Pelletization equipment is expensive and not well suited for small research scale batches of synthetic polymers targeting the development of new and novel polymer architectures.? For this reason, we are investigating polymerization methods that produce sand like polymer product directly from the reactor that can be used in injection molding equipment without pelletization.? Specifically, we are investigating suspension polymerization of styrene using polyvinyl alcohol as the suspending agent.? Results of the synthesis, process optimization, injection molding, and materials testing procedures will be discussed.
