Polybutadiene in Impact Polystyrene

Polybutadiene (or rubber) is added during polymerisation of styrene to increase the flexibility of polystyrene polymers. It is important to closely monitor the amount of polybutadiene added, so that the flexibility of the polystyrene polymer may be regulated.

This application note outlines how Nuclear Magnetic Resonance can provide an effective and rapid
method for the regulation of polybutadiene content in Impact Polystyrene.
