Descripción

Application

2,2′-Azobis(2-methylpropionitrile) (AIBN) is a radical initiator. AIBN solution can be used to initiate radical-induced reactions, specifically free-radical polymerizations. It can be used in:

• Synthesis of styrene-vinyl pyridine diblock copolymers by reversible addition-fragmentation chain transfer (RAFT) polymerization.
• Preparation of silicon oxycarbide glasses.
• Synthesis of poly [N-(p-vinyl benzyl) phthalimide] for the preparation of titanium dioxide composites for electrophoretic displays.
