Azobisisobutyronitrile → HCID 168686, compound

Participants

Reaction Conditions

Reaction Steps

Polymerization was initiated with a solution of 21.7g of ethyl acrylate, 50g of butyl acrylate, 3g of acrylic acid, 2g of azo-bis-isobutyronitrile and 02.g of lauryl mercaptan in a reactor by slow heating, starting at 25° C. The polymerization started vigorously at 55° C. The main part of the polymerization was carried out between 100 and 120° C. by a slow addition of 250g of the same monomer mixture over a period of two hours with external waterbath cooling. Since stirring becomes difficult at this state, the material was removed from the reactor and heated for two additional hours at 120° C. The polymer material was highly viscous with comonomer proportions of 67:28:5.
