Product description

TMG-AIBI is a non-nitrile, cationic water-soluble azo polymerization initiator. It is highly effective for the polymerization of water-soluble vinyl monomer. The 10-hour half-life temperature is as low as 44 °C, and the product is active at low temperatures. TMG-AIBI finds widespread use in flocculants, super absorbent polymers, and finishing agents for textiles and wool.
