Azobisisobutyronitrile → Prop-2-enenitrile--ethenylbenzene (1/1)

Participants

Reaction Steps

A styrene-acrylonitrile copolymer resin (SAN) is synthesized by mixing 75 parts by weight styrene, 25 parts by weight acrylonitrile and 120 parts by weight deionized water; adding 0.2 parts by weight azo-bis-isobutyronitrile, 0.4 parts by weight tricalcium phosphate and 0.2 parts by weight mercaptan-based chain transfer agent to the above mixture; raising the temperature from room temperature to 80° C. for 90 minutes; and maintaining at this temperature for 180 minutes. The product is washed, dehydrated and dried to form a powder of the styrene-acrylonitrile copolymer resin (SAN).
