Two Methods of Preparing Thermosetting Hydroxyl Functional Acrylics

TABLE 1-23 FORMULATION FOR THERMOSETTING HYDROXYL ACRYLIC RESIN 

Charge monomer tank and thoroughly mix at ambient temperature. Charge initiator tank. 

Charge reactor with solvents and heat to 13S°C while stirring. 

Add the monomer charge from the monomer tank over a period of three hours to the solvents in the reactor at 135°C. At the same time feed in the initiatorfrom the initiator tank at a rate to coincide with the monomer feed rate. 

Add tert butyl perbenzoate if required and hold at 135°C until non-volatile content approaches 50%.
